E-government systems include_E-government systems should be built according to business characteristics

Today, with the country vigorously promoting the integration of e-government resources, and with the development of SOA architecture technology and software reuse technology, the information construction of ministries and commissions has generally shown a platform-based and service-oriented development trend. In this trend, various ministries and commissions need to choose the technical route to build an e-government system platform based on their own business characteristics.

In 1993, the Chinese government launched the "Three Gold Projects" of Jinqiao, Jinguan and Jinka. The e-government of ministries and commissions has since entered a period of accelerated construction. Up to now, a pattern of e-government construction has begun to take shape and is developing rapidly. situation. However, the application system construction of some ministries and commissions is mostly "built on demand", and with the continuous establishment of new systems, a situation where different systems are gradually formed. In some ministries and commissions that have done a good job in informatization construction, the informatization department needs to maintain hundreds of systems, large and small. A large number of systems have inconsistent implementation technologies and inconsistent data formats, which makes it difficult to reuse functions between systems and make integration difficult.

In order to solve the problems of duplicate construction and data islands, many ministries and commissions have been exploring the establishment of information system platforms based on SOA architecture technology, while strengthening the construction of information standards and specifications. The platform-based system construction method requires the establishment of an application system on the basis of a unified platform, which provides general software and basic data such as SMS, electronic signatures, GIS, and databases. This approach achieves the unification of technology and data between systems and the reuse of public components.

Technically speaking, the e-government system platform has three levels, and the difficulty of unifying these three levels varies.

The most basic is a unified data platform, which has a unified data model and a database management system that stores shared data. As technologies such as data warehouse and master data management gradually mature, a unified data platform has also been realized to a certain extent.

The second level is a unified technology platform, which is a platform formed by common technologies such as databases and middleware. Because the technology platform has nothing to do with the business, it is easier to unify. However, there are also promotion difficulties caused by the transformation of the original system.

The third level is the unified business platform, which is a system established based on the public business logic and rules of each system. It is physically a combination of public business components and services. Due to the diversity and variability of business logic and rules themselves, it is most difficult to implement a unified business platform.

Take the Jincai Project as an example. The "Application Support Platform" is the main content of the first phase of the Jincai Project, which includes construction at both the business and technical levels. In terms of business, the platform is the organizational storage center for core business data, reflecting comprehensive data relationships, providing global fund compliance control information, and integrating the core information of budget indicator flow, capital flow and control flow in parallel. Forming a data warehouse for first-level financial core business data; in terms of technology, the platform provides a variety of interface standards and reusable components to support the direct generation or effective integration of various surface business systems on the platform, becoming a hub for connecting various systems.

The implementation technology of the platform is different, the difficulty of implementation is different, and the applicable occasions are also different. In actual operation, the choice of platform technology route needs to be combined with the business characteristics of ministries and commissions. Generally speaking, ministries and commissions with vertical management and relatively mature businesses may consider adopting a unified platform as a whole due to their high business uniformity and strong management and control across the country. Ministries and commissions whose businesses are not very mature and are not vertically managed have strong personalized business characteristics and weak management. It is difficult to achieve a holistic unified platform and even more difficult to promote. Therefore, such ministries and commissions can focus on building a unified data platform and adopt a unified technology platform within a certain range; at the same time, in terms of business platforms, they should choose mature and stable businesses to form a business platform, and integrate GIS, media services, etc. The tool platform is combined into a basic business platform.
