Abstract: Based on the analysis of the problems of existing MVC persistence middleware, the realization approach of a four-tier object oriented persistence middleware is proposed, and a design pattern of object persistence is relatively completely realized. At the same time, the object-relationship transform algorithm is optimized and the complex associated objects request is realized. The results of comparative experiments show that the key indexes of the middleware are improved, providing a reliable data persistence technique for MVC-based MIS development.

Key words:  OOP persistence middleware, MVC framework, ORM, DAO
