Abstract:

Data persistence is an important problem of development in the process of designing enterprise application systems. Based on the analysis and comparison of the application of the Faade pattern, the generic DAO pattern, the Hibernate framework and the Spring framework, a universal solution is proposed for the data persistence layer based on the Faade pattern, which makes the loose coupling possible. And the data persistence layer is highly stable, flexible and expansible. Finally, the technology of the data persistence layer is applied to the information system of a telecom customer manager.
