Product Data Management Based On The System Architecture Of J2EE

The data management of the mechanical product is a technology that manages all the information and the process of the relative mechanical product. It is a integrating platform of the CAD/CAPP/CAM based on the distribution web work, client/server architecture, graphic user interface technique and so on. It is important in the course of the product development. But as the product data management system is a very big system, including lots of functions, if the product data management is build on the orthodox system architecture and the common way (Structure analysis method) is adopted, it will don't be equal to the requirement. With the Internet and www development, many new techniques are used in the product data management.In the paper, the Object-Oriented technique in the modem software engineering and the Unified Modeling Language is adopted. The analysis model of the product data management according to the Rational Unified Process is built. This is more satisfying people's logical thinking. Some ways to map the object model to the relative data model in the product data persistent store are summarized.Because the development of the product data management that based on the two ties Client /Server system architecture is very large and its flexibility, extension and transplant are bad, it don't fulfill the requirement of the modem Internet work, so author bring forward the idea that the product data management system is base on the multi-ties Browse/Server system architecture and analyzes the resolve plan-J2EE. Because the architecture of the J2EE is a flexible distributive software system, so this just solves the question that the product data management faces with. In additional, in the paper, the software component technique is applied in the development of the product data management system, the idea is that divide thecomponent of the big task into lots of ones of small task, which made the system more extensive.
