System Integration

The so-called system integration (SI, System Integration) is through the use of structured integrated wiring system and computer network technology, using technology integration, functional integration, data integration, mode integration, business integration and other technical means, separate devices, software and Information and other elements are integrated into an interconnected, unified and coordinated system, so that the overall function and performance of the system meet the requirements of use, so that resources can be fully shared and centralized, efficient and convenient management can be realized. The key to system integration implementation is to solve the interconnection and interoperability problems between systems. It is a multi-vendor, multi-protocol and architecture for various applications. This requires solving all integration-oriented problems related to subsystems, building environments, construction coordination, organization management, and staffing of interfaces, protocols, system platforms, and application software between various types of devices and subsystems.

As an emerging service method, system integration is one of the most dynamic industries in the international information service industry in recent years. The essence of system integration is the optimized integrated planning design, a large-scale integrated computer network system, system integration including computer software, hardware, operating system technology, database technology, network communication technology, etc., as well as product selection and matching of different manufacturers. Integration, the goal of system integration - the overall performance is optimal, that is, all components and components together can not only work, but the whole system is low cost, high efficiency, well-proportioned, expandable and maintainable In order to achieve this goal, the system integrator's strengths and weaknesses are crucial.
