Study on the method of building data persistence Layer based on the data dictionary

In order to effectively reduce the workload arising from database model changes during the system development, through the research on the iBATIS and data dictionary, doubly persistence layer would be established during the database system development, that is, based on data persistence Layer, we should build data dictionary persistence Layer and business layer of data dictionary which could effectively reduce the workload of database management to achieve the maintenance of the database model and data persistence layer. This technology would meet the demands of development and this framework was transplantable, easy to maintain.
