Based on design and development of network file management information system,the design of database conceptual model,logical structure and physical structure are analyzed.Meanwhile,the conversion of database conceptual model to relational model is studied and the method of systematic design based on E-R is also proposed.After an in-depth analysis of the standardization of database model,and a consideration of specific development needs and its environment,the data model is optimized and adjusted.Finally,specific solutions and technical measures are given to the file management information system with numerous and complex data information.
