LU Cheng-jun · Jisuanji gongcheng yu sheji · 2007
In the development and application of database,the operational part of the database is crucial,it can affect the operational function of the whole system.A system design with multilevel model is introduced,in which the access facility of the database is packed in different functional modules,which forms a level of data access.In this way,the complexity of the bottom operation and the diversity of the varieties of databases are avoided,and a scientific measure and practical technique for the implementation of the efficiency,stability and maintainability of the application system is provided.
