With the wide application and popularization of computers, it is important and urgent to study computer in universities. In view of students' lack of pertinence and practicality in the process of learning computer, teachers can improve students' practical skills by using multimedia, network resources, courseware making, network management software, and building a communication platform between teachers and students. The following computer papers are recommended by me for your reference.

Computer model 1: architecture of real-time database for power grid dispatching

Real-time database system

The traditional real-time database stores real-time data in the server, and users operate the real-time data through the access interface provided by the real-time database system. Distributed real-time database system is the result of mutual penetration and organic combination of real-time database technology and network technology [6]. Distributed real-time database system is very different from centralized real-time database system in architecture, and has the characteristics of data distribution and logical integrity [7]. Data distribution means that the real-time database stores real-time data on different computer nodes through data segmentation, and users do not need to care about the physical location distribution of data, and complete transparent access to real-time data through data positioning between servers; Logical integrity means that these data stored in different nodes are logically interrelated and logically form a data whole. The distributed real-time database adopts the principle of unified global management and autonomous region segmentation management. The system divides the data reasonably according to the actual needs, and ensures the integrity and consistency of the data by means of redundant backup and data synchronization. The structure of distributed real-time database is shown in figure 1. The data distribution of wide-area distributed real-time database system ranges from data distribution on different servers in local area network to data distribution among different systems in wide-area network. The data on each system is managed by the local real-time database management system, which has a high degree of autonomous processing ability and can independently complete local business. The wide-area distributed real-time database expands the distributed real-time database into a wide-area system, and logically integrates the independent real-time database system in the wide-area network into an integrated large-scale distributed real-time database system, as shown in Figure 2.

Wide-area distributed real-time database architecture

At present, centralized data storage and processing technology is widely used in real-time database systems, which can no longer meet the needs of real-time processing, decentralized storage and wide-area global calculation of massive data in large power grid dispatching. In order to support intelligent dispatching service more efficiently and stably, it is necessary to change the existing real-time database architecture, and research and design a distributed real-time database architecture suitable for wide-area power grid dispatching. The wide-area distributed real-time database system consists of real-time database systems distributed in multiple dispatching systems in a wide area. Through the unified data operation and access mechanism, the transparent access to the data of each real-time database system is realized, so that the wide-area distributed real-time database can be regarded as a complete database in use, but it is actually distributed in several geographically dispersed power grid dispatching systems. The architecture of wide-area distributed real-time database system adopts service-oriented architecture, which includes file system layer, data processing layer, network connection layer, data positioning layer and application layer from bottom to top, and consists of application program interface (API) service interface, wide-area real-time database data positioning system and in-system real-time database service processing system. The architecture of wide-area distributed real-time database is shown in Figure 3. In this framework, the functions of the file system layer include storing distributed real-time database entities, handling redundant data backup and data synchronization between wide-area systems. The data processing layer is responsible for processing specific data access requests and data release, as well as data encryption and data synchronization between redundant systems; The network connection layer is responsible for data security authentication between systems and connection management between local area network and wide area network. The data positioning layer is responsible for wide-area data positioning, SQL parsing of structured query language, establishment and management of wide-area data index; The application layer includes all upper business applications of power grid dispatching automation system. Applications can access the real-time database by calling API interface or SQL, including request response and subscription publishing. It is the end user of wide-area distributed real-time database system.

Key technologies of wide-area distributed real-time database system architecture

The architecture of wide-area distributed real-time database can solve the bottleneck problem of data storage and access in dispatching automation system, the problem of data interaction and sharing among dispatching systems, improve the ability of information processing, calculation, storage and sharing, improve the execution speed and processing ability of the system, and better serve the integrated implementation of large power grid. The research and development of this architecture needs to focus on the key technologies such as wide-area data identification, wide-area data decentralized storage, wide-area data service positioning, wide-area redundant backup and data synchronization, and wide-area data secure access.

1 Unique identification method of power grid equipment

At present, the equipment identification keyword in real-time database system is unique in this system, which can not meet the requirements of interactive sharing between distributed data storage and scheduling systems in wide-area system. It is necessary to design a unique keyword implementation method in the wide-area system, and the keyword needs to add information identifying the area where the data belongs to identify the system area in the wide-area distributed real-time database system. In this way, in the whole power grid dispatching automation system, each device corresponds to a unique device identifier in a wide area. With the introduction of the unique identification of wide-area devices, the real-time database of each sub-area only stores the records of its own area, thus realizing the decentralized storage of wide-area data. In addition, the design of this keyword can also be used for data location, and the wide-area distributed real-time database system can directly locate the system to which the record belongs by analyzing the keyword, thus completing the location of wide-area data resources.

2 unified naming method for power grid equipment

In a wide-area distributed real-time database system, data interaction between systems can be based on device names or device keywords. To a great extent, the way of interacting with equipment names depends on the standardized naming of power grid equipment in a large range to ensure the uniqueness of power grid equipment names in the whole system, which is also the basis of smooth data flow in the whole dispatching technical support system. The unified naming method of equipment in wide-area distributed real-time database system can refer to the Naming Specification for General Data Model of Power Grid Equipment issued by State Grid Corporation. The naming structure of power grid equipment is as follows: power grid, power line/voltage, interval, equipment/components and attributes. Through this naming convention, for a given device name, the system to which the data belongs can be located through the "power grid"; Locate the corresponding data in the sub-area through "station line", "voltage", "interval", "device" and "component"; Navigate to the property value of the data through Properties.

3 real-time data distributed storage technology

The distributed storage of wide-area distributed real-time database is divided into two parts: the distributed storage of data between wide-area systems and the distributed storage of data within local systems. For the former, in order to adapt to the current situation of hierarchical management in scheduling system, the tables in real-time database can be stored in different physical storage locations. Because most of the access to the real-time database in the scheduling system comes from the local area, all the data in the scheduling system should be stored locally, and redundant backups of the data in this system can be established in other scheduling systems. The data table of wide-area distributed real-time database forms a multi-level tree structure in physical distribution. Each node of the tree corresponds to the real-time data of a dispatching system in the system, its child nodes correspond to the real-time data of lower-level dispatching systems, its parent nodes correspond to the real-time data of upper-level dispatching systems, and its brother nodes correspond to the real-time data of the same-level dispatching systems. Taking the circuit breaker equipment list as an example, the wide-area distributed storage structure is shown in Figure 4. For the latter, we can refer to the distributed storage mode of distributed databases such as MongoDB[8], select keywords or devices to be uniformly named as the key values of distributed storage, and dynamically and transparently store data on each server according to load balance.

4 Real-time data service positioning technology

The positioning system of wide-area distributed real-time database service needs to analyze the keyword information of real-time data and obtain the regional information of real-time data from the given information. If real-time data in the system is needed, it can be obtained through the local area network of real-time database. If you access the real-time data of a remote system, you should first judge the specific system where the data is located, obtain detailed network information through location service, and finally obtain the corresponding data from the remote system, so that all real-time database systems in the wide-area system form a "real-time database cloud" similar to that, and realize transparent access to real-time data in the wide-area range. The feasible method to locate wide-area data is to locate by device keywords or device names. The real-time data of different systems are all marked with unique equipment identification or equipment name in the whole wide-area system, and the API interface can quickly locate the system to which the power grid equipment belongs according to the equipment identification or equipment name sent by the application.

5 Real-time data indexing technology

Database indexing is an important way to improve the efficiency of data query. At present, the index technology in real-time database system includes B+ tree index and hash index which are suitable for different purposes. In the wide-area distributed storage environment, indexing is not only a means to improve query efficiency, but also a method to quickly locate wide-area data. The unique identification of wide-area power grid equipment provides a way for the system to locate by keywords, the unified naming of wide-area equipment provides a way for the system to locate by device name, and the wide-area decentralized data index provides a way for the system to locate by certain attributes except keywords and device names. In addition, we can also use indexing technology to establish a buffer mechanism for data retrieval, that is, to establish a buffer index between the unified naming of devices and the keywords of wide-area devices. In use, the application layer uses the unified naming of devices to access the real-time library, instead of using relatively obscure keywords, and the bottom data access of the real-time library uses keywords to retrieve data. This access mode is more convenient for application-layer programs, and the efficiency of access can be guaranteed by caching indexes.

Real-time data redundancy backup technology

In a wide-area system, it is necessary not only to establish redundant nodes between different servers in the system, but also to establish a system-level redundancy mechanism between systems. The redundant backup technology of real-time database between wide-area systems needs to realize one-way and two-way backup between two or more systems. Taking the dispatching of China Power Grid and China Power Grid as an example, the "1+3" mutual backup mechanism can be adopted to construct an "integrated mutual backup" system, as shown in Figure 6.

7 Real-time data synchronization technology

Data synchronization between wide-area systems can be divided into real-time synchronization and quasi-real-time synchronization. Real-time synchronization requires strong consistency of data between redundant systems [10], which is easily affected by the network environment between wide-area systems and will reduce the autonomy between systems. Real-time synchronization is generally not considered. Quasi-real-time synchronization allows synchronization between nodes to proceed asynchronously. When a node changes, other synchronous nodes can synchronize this change with a certain delay, which can reduce the operation failure caused by abnormal factors and improve the system availability. According to the CAP theorem of distributed systems [1 1], distributed systems cannot satisfy consistency, availability and partition tolerance at the same time. For the whole wide-area power grid dispatching system, the guarantee of availability is beyond doubt; The tolerance of partition slot ensures that a subsystem can be used normally when the network is disconnected, which often happens and needs to be guaranteed; On the premise of ensuring availability and slot tolerance, the balance between CAPs can only be maintained by partially sacrificing "consistency". The data synchronization between different redundant nodes in each system of wide-area distributed real-time database system can adopt the current synchronization mode in a single system, while the data synchronization between redundant systems adopts the quasi-real-time synchronization mode. From the result of data synchronization, we don't need strong consistency of data, but only weak consistency and final consistency of data [12].

8 Real-time data security access technology

Wide-area distributed real-time database serves multiple sets of power grid dispatching automation systems between wide-area systems, so it is necessary to study the data security access technology between multiple systems in wide-area environment. At present, the power grid dispatching automation system has built a three-level deep security protection system, and different systems are encrypted and authenticated by authentication equipment. The data security access between wide-area systems should be established on the power grid dispatching automation system, and the data security access between wide-area systems should be realized by means of encryption, authorization and authentication.

Application prospect

With the construction of UHV interconnected power grid, the demand for safe and stable power grid integration is getting higher and higher, and the application of wide-area distributed real-time database system in power grid dispatching is of great significance. 1 wide area distributed real-time database system can meet the needs of "integration" implementation of large power grid. At present, in the system construction of national/network/province integration, province/prefecture integration and prefecture/county integration, the integrated application has shown great advantages, including integrated state estimation, integrated network analysis and integrated dispatching simulation. Wide-area distributed real-time database can provide a new way to store and access real-time data for these integrated applications, making real-time data sharing between multiple systems faster and more efficient. 2. Wide-area distributed real-time database can meet the needs of disaster recovery and backup of power grid dispatching system. In recent years, natural disasters occur frequently in China, which puts forward higher requirements for redundancy and mutual backup ability of power grid dispatching system. At present, all levels of dispatching are strengthening the construction of standby dispatching and improving the disaster tolerance of power grid dispatching. The redundancy and mutual backup function of wide-area distributed real-time database can greatly improve the mutual backup ability between dispatching systems in wide area, so as to realize the application access of dispatching systems without geographical restrictions, improve the reliability of backup systems, and further improve the stability and security of power grid dispatching systems in the whole wide area network.

This paper analyzes the present situation that the real-time database of power grid dispatching automation system can only provide real-time data services in local areas of the system, but can not support the storage and sharing of wide-area real-time data between systems, introduces the characteristics of distributed real-time database system, puts forward a wide-area distributed real-time database system architecture for power grid dispatching, meets the requirements of "integration" of interconnected large power grids, discusses its key technologies and gives an application example. The architecture of the wide-area distributed real-time database system proposed in this paper adopts the service-oriented architecture in design, which is the wide-area distributed extension of the current real-time database system and meets the multi-level management requirements of the dispatching system for wide-area data distributed processing. This architecture can solve the problem of real-time data interaction and sharing between power grid dispatching automation systems at all levels, and improve the redundant backup ability between systems, thus improving the dispatching ability of super-large power grid and ensuring the safe and stable implementation of power grid.

Computer Model 2: Research on the Construction of Local Cultural Database

Many cultural resources in Anhui are precious cultural heritage. For example, local chronicles contain a large number of social, political, economic, cultural and other historical materials, which have the functions of preserving history, managing resources and communicating. Through genealogy, we can learn about major historical events, rural history, clan history, family history, scenic spots and historical sites and customs related to clans, which is of valuable historical value; Handwriting has both historical reference value and appreciation collection value, which has become the epitome of traditional culture ... The characteristic cultural database can preserve and protect all kinds of cultural resources for a longer time through digital technology and equipment, and provide them to readers through words, images, videos, audio and other forms with the help of the Internet and electronic equipment, which can further enrich and improve the resources on the public cultural service platform and improve the coverage of cultural information resources for the whole population.

Anhui's cultural characteristics are as follows: free publicity, seeking change and innovation, seeking truth and being pragmatic, learning Shang Xian, and seeking truth and being pragmatic. These five aspects depend on each other and complement each other. * * * together constitute the essence and soul of Anhui culture [2]. The establishment of this database further enriches people's ways of understanding, contacting and utilizing Anhui's local cultural resources, enables more people to understand Anhui's characteristic culture, appreciate the essence of Anhui's culture and feel the influence of Anhui's cultural spirit, helps to enlighten and educate the public, carry forward and inherit Anhui's excellent culture, advocates the formation of ideas and values that can promote social progress, promotes the construction of a socialist core value system, and provides strong ideological guarantee, spiritual motivation and intellectual support for the goal of "building a strong cultural province" in Anhui.

Present situation and existing problems of Anhui characteristic culture database construction

From 2065438 to February 2002, the author logged on the websites of 30 undergraduate libraries and provincial libraries in Anhui Province, and investigated the Anhui local cultural databases established by each library through links such as "featured collections" and "featured databases".

1 Anhui characteristic culture database construction status

1 Anhui Library Database Construction Anhui Library, as an Anhui branch of the National Cultural Information Resources Sharing Project, has completed Anhui Fine Arts, Southern Anhui Incident, Huizhou Architecture, Anhui Road and Bridge, Anhui Tourism, Anhui Genealogy, Anhui Opera, Anhui Sage, Celebrity Handwriting, Anhui Seal Carving, Huizhou Puxue, Tongcheng School Literature and Genealogy. Produced TV feature films such as Anhui Flower Drum Lantern, Huizhou Architecture, Anhui Famous Historical and Cultural City, Anhui Red Memory and Anhui Traditional Craft, and introduced cultural celebrities, traditional arts and crafts, architecture, local operas and historical events in Anhui in the form of words, pictures and videos. 2. Construction of university libraries

2 Anhui characteristic culture database construction status analysis

It can be seen from the survey results that at present, anhui library and some university libraries have built some databases with Anhui characteristics in combination with their own resource characteristics, and achieved gratifying results, which have played a certain role in the storage and publicity of Anhui culture, but there are still some problems to be solved urgently: the construction of 1 database needs to be planned as a whole. The survey results show that anhui library enjoys building projects with the help of national culture. A number of Anhui cultural databases have been established and made available to the public through the Internet. You can view the resources of each database under the "Characteristic Collection" set on the homepage, but without scientific and reasonable classification and organization, people can't fully understand the characteristics of Anhui characteristic culture. Of the 30 university libraries, only 10 has established 19 Anhui culture-related database, accounting for only 1/3. In addition, because most databases are based on characteristic collections, there is a phenomenon of repeated construction. For example, Hefei University of Technology and Anhui Institute of Architecture have Huizhou architecture databases, and Hefei University of Technology and Hefei University of Technology have Li Hongzhang's characteristic databases. The construction of database needs unified planning, unified leadership and collaborative construction, and it needs to formulate various security mechanisms and rules and regulations that are conducive to construction and use, otherwise it will not only guarantee the quality of database construction, but also cause waste of people, money and materials. A large number of cultural resources need to be digitized. The library in Anhui Province has a large collection of cultural heritages, such as Huizhou ancient books, Huizhou documents and Huizhou genealogy collected by Huangshan University Library, books on Nuo culture, Buddhist culture and local history collected by Chizhou University, and Anhui carved books and genealogy documents collected by Anhui Library. According to statistics, there are more than 6,000 kinds of works about Hui classics and history, and nearly 3,000 kinds have been circulated in the world. Most of them are collected in libraries, museums and other units in Anhui. There are more than 65,438+065,438+040,000 volumes of ancient books in Anhui public library, university library and cultural and artistic institutions [3]. However, in the cultural relics database and notes of the provincial library, only some fine works have been made for readers, and a large number of tracks, images, rubbings and genealogies have not been included in the database, and many precious cultural resources have not been fully utilized. 3. The social benefits of the database need to be improved. In the investigation, it was found that the databases built by various units were basically not open to all the public. For example, in the database of the provincial map website, ordinary users can only see the text introduction, pictures, cultural relics and genealogy of a certain track. And video materials can only be used in Hefei. In the 19 database established by university library, only five off-campus readers can browse some resources. Due to the lack of extensive social publicity, limited resources can only be known and used by a few people, and the database still has great potential in popularizing and popularizing Anhui culture. 4. The standards and specifications of database construction must be unified. Because of different database construction software, different data format standards, different databases' structures, different user interfaces, different retrieval methods and different retrieval results, it has set obstacles for the future integration and unified retrieval of these databases. In the face of one database after another, it is not only necessary to repeat the retrieval, but also to manually screen the retrieval results to eliminate duplication, which consumes more time and energy for users. The gap of database quality is expected to narrow. The differences in the ability and quality of database builders in different libraries will affect the quality of databases. For example, some libraries only have text-based databases and have no retrieval function; However, some libraries have established multimedia resources integrating text introduction, audio, video and animation, and provided various retrieval channels. In the network era when new technologies are constantly emerging, the construction of database should consider how to attract users and facilitate their use through advanced technical means. Therefore, the construction of database puts forward higher requirements for the professional quality and skills of staff.

Tentative ideas on the construction scheme of Anhui characteristic cultural database

1 overall planning leader

The construction of Anhui characteristic culture database involves the cooperation of libraries, archives, local records offices, cultural centers, museums, party history offices and other units, as well as the collection of local resources at all levels. This is a huge system engineering, which needs to be guided and controlled from a macro perspective. Anhui Province should set up a special organization in the form of archives, headed by the Anhui Provincial Department of Culture, responsible for listening to the construction report, coordinating the work of all parties, responsible for or assisting in solving copyright problems, and making overall decisions. Anhui library is responsible for the specific leadership of the construction, and made a database construction plan. University libraries and public libraries at all levels are responsible for building libraries, while cultural centers, archives, museums and other cultural units are mainly responsible for collecting. Anhui University has Huizhou Cultural Research Center, Anhui Normal University has Weinan Historical and Cultural Research Center, and Huangshan College has Huizhou Cultural Information Center. These units have studied Anhui culture for many years. Therefore, the construction of Anhui characteristic culture database should seriously listen to the opinions of experts from these institutions, formulate detailed, scientific and operable plans, and adjust them in time according to the actual situation to ensure the smooth construction of the database.

2. Establish a safeguard mechanism

Because the construction of Anhui characteristic cultural database is not a one-off event, nor is it a one-off event, in order to ensure the smooth development of the work, it is necessary to formulate the work system, division of responsibilities, work rules and so on. In order to stimulate the enthusiasm of relevant units and ensure the quality of the database, it is necessary to establish an assessment mechanism, an evaluation mechanism and an incentive mechanism, and the provincial library is responsible for guidance and supervision. In order to ensure the long-term construction, use and maintenance of the database, Anhui * * * should set up a special project to allocate special funds for database construction, and at the same time formulate a long-term investment mechanism for funds, and stipulate a certain proportion of financial investment at all levels every year to ensure the sustained and stable development of database construction and subsequent effective maintenance, and ensure the good construction and use of the database.

3 determine the principles of inclusion

Anhui has a profound and unique cultural heritage, and the characteristic cultural resources that can be included in the database are extremely rich. The following principles should be determined in the construction of characteristic cultural database: the scope of 1 should be "complete". The database resources should involve cultural policies and regulations, strategic planning, economy, cultural activities, population, minerals, human environment, geography, social production, historical events, historical celebrities and their activities, historical sites, folk customs, religion, production technology, literature, art and so on. For example, the political, economic and cultural background of the existence and development of Anhui characteristic culture and the unique conditions of the region [4]. 2 The contained type should be "wide". There should be not only the arts, handicrafts and customs handed down from the people, but also all kinds of documents on carriers such as bamboo slips, wooden slips, silks, ceramics, paper and magnetic media, as well as physical ancient buildings, temples, ancient battlefields, ancient tombs, cliff stone carvings, inscriptions, calligraphy and painting. There are entities and virtual ones; There are dynamic and static. 3 The inclusion criteria should be "specialization". The ultimate goal of the construction of Anhui cultural characteristic database is to serve the social, economic and cultural construction of the region and meet the users' demand for documents related to local culture to the maximum extent [5]. Only in this way can this database be meaningful and valuable. Therefore, the database construction must grasp the main line of regionality, and must select those cultural resources that best reflect Anhui characteristics for collection, sorting, processing and warehousing. 4 recording time should be "wide". In terms of time, we should collect ancient, modern, modern and contemporary resources, including all kinds of historical remains, such as genealogy documents, genealogy, ancient battlefields and so on. And various cultural resources published in recent years, such as Millennium Huizhou Dream, A Journey to Ancient Huizhou, History of Cao Yun, Huizhou Past, etc.

4 Unified database construction software and standards

The establishment of Anhui cultural characteristic database is a process of multi-unit division of labor and cooperation. It is necessary to determine the basic contents and main undertakers of each sub-database, select appropriate application software, formulate and follow the database construction standards, and standardize the record format, classification system, communication standards, metadata standards, retrieval language standards, security standards and evaluation standards of the database, so as to realize the standardization of the database. In view of the fact that the anhui library Anhui cultural database has begun to take shape, there are two ways to build the Anhui characteristic cultural database: one is to further enrich the content of the database and give each library an institutional account for processing, making and inputting materials; Second, according to CALIS "Basic Technical Specification for Local System of Sub-projects of Characteristic Library" and "Relevant Rules for Metadata Specification of Sub-projects of Characteristic Library" and other data construction specifications and indexing rules, the database is built, which not only ensures the reliability, systematicness, integrity and compatibility of the database, but also helps to realize the * * * resource sharing with national universities in the future [6].

5 Scientific design of database structure

A good database, structural framework design is directly related to the classification and utilization of resources. According to the types of Anhui cultural resources, the author puts forward the main framework of Anhui characteristic cultural database as follows, and the specific columns can be added, deleted and changed according to actual needs. Among them, music and dance include music scores and videos of folk songs, minor, Buddhist music, Taoist music, flower drum lanterns, Nuo dance and so on all over Anhui; Opera acrobatics includes the introduction of operas, biographies of actors, and video materials of precious aria. Huizhou architecture includes the introduction, pictures and videos of Huizhou architecture; Arts and crafts include the general introduction of Anhui arts and crafts, the historical evolution of various crafts, artistic characteristics, artwork pictures, etc. Local documents include local cultural laws and regulations, as well as local chronicles, genealogy, genealogy, historical documents, local yearbooks, etc. Religious folk customs include Taoism, Buddhism, local customs, temple fairs and other local activities in Anhui; Anhui seal cutting includes checking the list of seal carvers, collecting books and seals, and appreciating Mo Bao's handwriting carved by some famous Anhui writers or Anhui people. Historical resources include famous historical events, historical celebrities and their activities, notes, manuscripts, literary works, original paintings and calligraphy, etc. Monuments include monuments, sites, stone carvings and inscriptions in Anhui.

6 adhere to the purpose of * * * construction * * *

The construction of Anhui characteristic cultural database should adhere to the principles of cooperation, * * * co-construction and * * * sharing. All units should clarify the division of responsibilities and the characteristics of resources, talents and technology, and give full play to their respective advantages on the basis of making full use of existing conditions. Provincial libraries should not only further speed up the digitalization of their own characteristic resources, but also guide the construction units of branch libraries to carry out their work. Cultural centers, museums and other cultural units mainly collect resources and assist libraries in database construction. Libraries should combine local culture and specific division of labor, collect cultural resources in a certain field as completely as possible, do a good job in digital processing of resources, and set different reading rights for different library readers through hierarchical browsing of catalogues, abstracts and full texts, so that readers with resources can read full texts and other readers can read abstracts. At the same time, interlibrary loan and reference services can be carried out to meet the specific needs of more readers.

7. Pay attention to the cultivation of professional talents

Different types of resources need different database construction methods. For example, for some paper resources, it is relatively simple to use database building software directly; For some opera vocals, it is necessary to record, take photos, record music, write lyrics and make audio-visual materials; For ancient dwellings, videos, photos, lyrics and picture books are needed. Therefore, in addition to the professional knowledge and skills of the library, processing personnel should also master computer application technology, network technology, photography technology, image processing technology, audio processing technology and so on. Provincial libraries should not only organize specialized skills and application training, but also establish communication platforms such as QQ groups or forums to facilitate the exchange and discussion of relevant personnel, thus improving the quality of the database.

8. Strengthen resource publicity and user training.

Good resources must be known and used. Let people know that we should publicize it through various channels, make it deeply rooted in people's hearts, let the public know that there is such a database, and know what resources this database can retrieve and use. Of course, "it is better to teach people to fish than to teach people to fish." When people know this database, they should teach users how to use it through various forms of training, so that this database can really play a role in enhancing cultural soft power.
