This paper introduces the special demand of general information publish system and the database modeling based on the demand. It focuses on the application of UML and ERA model in its demand analysis and logical modeling. The theory of normalization is used to reduce the redundant data of the database and promote the maintenance of the system. Finally, a brief direction about system realization based on database modeling is given.
