The informatization of construction enterprises has gone through the development process from enterprise LAN with single computer system, from simple word processing to office automation, from isolated construction management system to Internet system integration. Its system includes a series of related information and processing systems such as construction plan, budget, valuation, finance, materials and archives. These data information and systems are relatively independent and interrelated.

2. How to establish a project information management system?

To establish an information management system in an engineering project, we must first make an objective and systematic analysis of the project construction, determine a scientific and effective engineering project decomposition structure and organizational decomposition structure, and let all parties involved in the project show how to determine the project management objectives and bidding control objectives by each part as a whole, clarify the hierarchical relationship between departments, and determine the information flow route.

3) The difference and connection between them.

Any management activity is inseparable from the processing of certain information. Construction enterprise workers

The management activities in all aspects of the project are not isolated, but interdependent and mutually restrictive. Therefore, it is necessary to exchange and transmit information in management activities. The complexity and heaviness of project management in construction enterprises directly determine the characteristics of complex and frequent information flow in the process of project management. 4) Architecture diagram
