Liu Qi-chao · Jisuanji gongcheng yu sheji · 2007
A kind of architecture of two layers data access is designed.The first layer is between client application and data access mid-dleware,which is designed for organizing data and calling data access functions of middleware.The second layer is data access mid-dleware,which is for exchanging data between database and client application.While designing data access middleware,elastic data accessing patterns are pointed out,according to design pattern.Then some comparisons are made among these patterns and pointed out every function of the class,their inter-connection and the expand way.Finally the one is boiled.
