Design And Implementation Of Data Maintain System Based On Potevio Management Information System

The data maintenance system mentioned in this paper is based on Potevio management information system(MIS), this system use these followed technologies, like database middleware technology, serializing object technology and so on. This paper build a new way to backup, to restore, to transplant and to upgrade database. As we know the J2EE technology is used more and more, many company used this technology to develop their MIS, Hibernate is a tool to store object data to relational data, and it is a useful part of J2EE.Object-oriented(OO) technology is more and more popular right now, and object relation mapping tools(ORM) is used a lot. So the data maintain system is very important to the MIS that used ORM technology, but right now there is no very good solution to that. This paper talk about the theory and technology of data maintenance based on ORM technology, and design and realize a data maintenance system.The main four functions of this data maintenance are backup database, restoring database, transplanting database and upgrading database. According to the 00 technology, design a new way to backup the database, first getting the relational data, and mapping to object data by using ORM tools, second serializing the object data to files. According to the system irrelevance of Java objects so this kind of backup file have a lot of advantages of object, then we can use the object-oriented technology's advantages. The functions of this system is based on these advantages. The special of this kind of backup file is that there is no difference to the database management system and no difference to operation system, by using this special advantages this paper realize those four functions. Those four functions are based three main core modules. This paper is all talk about how to design and realize these three modules.
