Research and implementation of an efficient data persistence model

Data persistence is a part of important enterprise-level application system, using technology on object-oriented and relational database to develop project is a difficult thing. This paper proposed a data persistence model based on the DAO (Data Access Object) pattern, through variable mechanism encapsulated the underlying data access independently, making the object model and relational database with independence. Similarly, by buffering mechanisms it can greatly enhance the efficiency of data access.
