Abstract: To solve the problems of rapidly increased projects, poor efficiency of project document management mechanism, lower security, difficulty to find documents, based on B / S mode, combined with the actual situation and needs of the company informatization, we applied J2EE framework technology to design and develop a set of Engineering Document Management System. The System consisted of 4 main functions, such as engineering document collection management, material management, hand over management, summary statistics, and system management. Compared with the existing engineering document management mechanism, the new System managed the document more rapidly, accurately and safely, improved the efficiency of project management.
