What is the system architecture of sap_sap system process and organizational structure

SAPNetWeaver technology platform includes the following five levels

1. Platform management layer

2. Process integration layer

3. Data Integration layer

4. Aggregation management layer

5. Release and access layer

Platform management layer

In this layer it is The base layer on which NetWeaver runs. Contains JAVA and ABAP operating environments and development environments. System security management and identity management, various monitoring and management tools, full life cycle operation and maintenance, monitoring, etc.

Process integration layer

At this level, SAP systems, such as ERP and CRM, can be implemented. Comprehensive process integration (A2A) between SAP and non-SAP systems can also achieve integration with external corporate systems, such as bank-to-enterprise direct connection (B2B). At this level, the enterprise's ESB bus can be implemented to build the enterprise's SOA application. Realize the integration between various business application systems of the enterprise, use SOA architecture to support the integration and interconnection between systems, ensure effective communication and sharing of information, and ultimately achieve the purpose of business collaboration. Provide a global business service platform environment, support cross-system service registration, service routing, service scheduling and other service mechanisms, support internal applications to establish a shared service layer between systems, and support batch data message exchange mechanisms based on message queues , providing an adaptation mechanism to realize the integration of legacy systems.

Data integration layer

This layer mainly includes two parts, data management and enterprise information management.

Data management mainly includes master data management and data integration services (master data & business data). At this level, the standardization and standardization of master data management are realized, thereby realizing the unified management and centralized maintenance of master data throughout the enterprise, and realizing the collaboration and distribution of these master data and various related business systems to ensure that the enterprise can manage heterogeneous information The system has accurate and unified high-quality master data, thereby promoting the improvement of business processes and increasing productivity.

At the same time, data integration services are also implemented at this level to provide data quality inspection, data cleaning and other services for process integration and data extraction to EDW (enterprise data warehouse).

At the same time, this level also realizes the enterprise's structured data management (enterprise intelligence) and unstructured data management (enterprise content management). At the same time, structured data and unstructured data can be integrated with each other to build an enterprise's knowledge system.

Aggregation management layer

At this level, it mainly implements business process management and aggregation applications of interfaces, information, and services. Through the establishment of business process management, services can be reorganized and the enterprise's business processes can be customized on demand. At the same time, during business process processing, various information and services can be aggregated to facilitate end-user decision-making and use.

This level will be the business operation platform of the enterprise. Business process is the intersection of business and information technology. As the top layer of SOA architecture, business process management is to ensure that information technology can be more flexible and effective. The foundation that supports enterprise business. Put existing and new applications under the direct control of business personnel, strengthen communication and communication between IT and business, allow business personnel to more easily optimize processes, realize cross-department and cross-system business process automation, and make business People can get real-time information about process status; allowing enterprises to more fully reuse services.

Release and access layer

At this level, it mainly realizes friendly human-computer interface interaction, multi-channel and multi-mode release and display. In the traditional way, users need to open the interface independently for access. Under the new method, data can be released through various channels, such as through large screens, through various Pads, through text messages and emails, through various smart phones and handheld devices, etc.

The user interface has four core functions: browsing, navigation, active push of customized information, and collection and analysis of user behavior data.

The user interface should be consistent, friendly, convenient and fast across terminals, platforms and operating systems.

At the same time, a unified account can also be implemented. Users can log in with one account to achieve single sign-on for all application systems.
