Design of Construction Project Drawing Censoring Information System Based on UML

In order to better the censoring of construction drawings, we research the process of censoring drawings from the point of information management system. Based on the UML modeling technology, we design models for each procedure of censoring drawings such as reception, distribution, censoring, reply, charging, approval, certification and inquiring. Through using case diagram, activity diagram, sequence diagram, class collaboration and relationship diagram, we discuss the process and methods of modeling based on UML, and implement the system by using .NET technology. Application of this system can normalize the censoring process, enhance the management level and work efficiency.
