Xia Sun, Chang Yao · 2011
Designing software to connect a relational database in an object-oriented business system is a tedious task. This paper proposed a data access framework based on design patterns, analyzed the Template Pattern, Proxy Pattern, and Factory patterns in the application of data access framework layer, encapsulated the underlying data access through the variable mechanism independently which kept independence of the object model And the relational database. Similarly, system increased greatly the efficiency of data access through buffer mechanisms.
