I. Background of the programme

With the continuous improvement of enterprise informatization, the enterprise IT system is becoming larger, the cross-system process and the system, as well as the internal interface requirements and interface service calls are also increasing.

At present, due to the excessive number of interfaces among the mutual systems and the lack of a unified management specification, the interface protocol is too wide, and the interface between the systems is network.

In order to meet the requirements of enterprise strategy development, combined with Enterprise Informatization Project Construction plan, the system integration is guided by service-oriented architecture (service oriented Architecture, short SOA), to start from business demand,

Maximize the reuse of existing software assets, reduce coupling, and better meet the business needs of users, to provide users with efficient, high-quality business services. Referring to the architecture, it considers the long-term goal and the immediate goal of the informatization construction, and clarifies the principle of the integrated platform, the whole structure of the system, the interface specification and the step implementation plan.

Ii. Introduction of the programme

Our careful analysis of manufacturing-related applications and streaming diagrams, combined with the successful experience of SOA, suggests the overall architecture, in which the bottom-up is mainly:

1. Enterprise Service Bus ESB: through a variety of protocols, such as HTTP, AQ, MQ, and other existing system joins, to complete the system in an SOA way interconnected. Communicate with different systems via protocol conversion of service bus without the need to replace the original system technology.

2. Business Process layer: through the workflow engine to achieve the flexible support of enterprise business processes, the separation of business process description and specific implementation, the application of Process control is the server to invoke specific business methods, improve application flexibility, more adaptable to the changing environment, for different business needs, rapid assembly of business services, Thus accelerating business innovation.

3. User Access layer: The Enterprise Portal provides the infrastructure needed to build and deploy an extensible portal site that enables users to access information at any time, anywhere, and on demand through an application integration platform.

Iii. Advantages of the scheme

1. Customized service Management Center;

2. Use cache in message flow to reduce the performance of relay consumption;

3. Improve the response speed of enterprises to solve problems;

4. The scheme has high availability, high reliability, distributed deployment, no single point of failure;

5. The scheme has high availability, high reliability, distributed deployment, no single point of failure;

6. Conduct unified authorization and identity authentication;

7. Be able to monitor the status of the service;

Iv. Business Value

1. Realize the unification of Business master data information, break the information island;

2. Be able to monitor the information of the service in real time, to provide the leader with quick decision;

3. Providing a unified portal for information;

4. Flexibility to adapt to business changes;

5. Monitor critical business interfaces;

6. Optimize business processes and improve economic efficiency;

7. Component reuse, reduce late development costs;

8. Loose coupling, high cohesion can adapt to business change of the latest IT architecture;

9. Service Management visualization, can be seen throughout the life cycle of services;

V. Related Products
