The specific contents of system integration
As a new service mode, system integration is an industry with the most vigorous development in the international information service industry in recent years. Overall design of system integration is the essence of optimization, a large-scale integrated computer network system integration system integration, including computer software, hardware and operating system technology, database technology, network communication technology, and different manufacturers, product selection, collocation integration, the overall performance of the system integration to achieve the goal of optimal. All parts and components not only can work together, and the whole system is extensible and maintainable system with low cost, high efficiency, shapely, performance, in order to achieve this goal, system integrators quality is crucial.
Integrated system (SI, System, Integration) is through the structured cabling system and computer network technology, the various separation equipment (such as personal computer), function and information integrated into interrelated, unified and coordinated system, make the resources to achieve full sharing, centralized, efficient and convenient management. System integration should include function integration, network integration, software interface integration and other integration technologies. The key to the realization of system integration is to solve the problem of interconnection and interoperability between systems. It is a multi vendor, multi protocol and application oriented architecture. This need to solve all kinds of equipment, system interface, protocol, system platform and application software and system, building environment, construction, management and personnel related to all oriented integration problems.
System integration has the following salient features:1: system integration to meet the needs of users as the fundamental starting point.2: system integration is not simply the act of choosing the best products, but the choice of products and technologies that best suit the needs of users and the scale of investment.3: system integration is not a simple supply of equipment, it embodies more design, debugging and development, is a highly technical behavior.4: system integration, including technology, management and business, and so on, is a comprehensive system engineering. Technology is the core of system integration, and management and business activities are the reliable guarantee for the successful implementation of system integration project.5: the performance price ratio is an important reference factor to evaluate the rationality and successful implementation of a system integration project.In a word, system integration is a kind of commercial behavior, and also a kind of management behavior. It is essentially a kind of technical behavior.
