Developing method for data base persistence layer based on JAVA

A development method for the JAVA-based database enduring layer: the object-oriented design mode is adopted, so that the database enduring layer can be abstracted. The alternated JDBC seal and package can be made between the JAVA and the database and a single port can be abstracted. The same operations can be sealed as the template; also, the tactic mode can be used to handle dynamically the results as per the client's demands. In addition, a simple port is used to quick access the database. The method for the data base manipulation and packing is that the JDBC API's various database operations are packed; also, the repetitive codes in the database interacting of the JDBC are formalized. The result reduction method is that as per the various demands of the client, extending the data set results. As per the different requirements displayed by the page, the result data set can be handled as the aggregating of List, Map or Bean and returned. Meanwhile, the JDBCUtils operation can be assisted; the batce operation
