Xian Hequn, Li Jing, Xiuqing Lu · Advances in intelligent systems research/Advances in Intelligent Systems Research · 2013
A dynamic database constraint definition method is presented based on metadata design, which facilitates clientside configuration of cloud database schema and consistency definition.The proposed scheme simplifies the conceptual schema designing process for cloud databases and offers more data administrative privileges to the user.It also enables the user to create new data tables and generate standard data access interfaces dynamically.A typical application of our method is introduced which solve the problem of dynamic factor management in a teaching management database.The implementation and application show that our method is effective and applicable.
