Remarkable features of information system integration

The information system integration project has the following significant features: (1) The information system integration project should meet the needs of customers and users as the fundamental starting point (2) Customer and user needs It is often not clear enough, complex and changeable, so we should strengthen the management of demand changes to control risks.

The command and dispatch system integration project is a typical information system integration project, which has the characteristics of a wide range of technologies and a long project cycle span. Project management of information system integration. Due to its wide range of disciplines, the relationship between the integrated parts of the information system integration project is complicated. How to effectively organize project management is the key to the success or failure of the project.

The characteristics of the information system integration project are different from other projects. The system integration project has the following remarkable characteristics. The information system integration project should be the fundamental starting point to meet the needs of customers and users.

System integration has the following remarkable features: 1: System integration should meet the needs of users as the fundamental starting point. 2: System integration is not a simple act of choosing the best product, but to choose the most suitable products and technologies for users' needs and investment scale.

Is the process of integrating the entire information system right?

The system integration of the information system is the integration of the computer system, that is, according to the needs of the application, the hardware ( Including systems, tools, etc.), the whole process of combining networks, databases and corresponding applications into a cost-effective computer application information system with practical value.

[Answer]: A Information system integration includes various tasks such as technology, management and business, which is a comprehensive system engineering.Technology is the core of system integration, and management and business activities are the guarantee for the successful implementation of system integration projects.

System integration is to integrate various separate devices (such as personal computers), functions and information into an interrelated, unified and coordinated system through a structured integrated wiring system and computer network technology, so that resources can be fully shared and centralized, efficient and convenient management can be realized. .
