Based On Needs Analysis And Framework Of The Personnel Management System Of The J2ee Architecture

With the steady improvement of the computers'hardware and the descent of the price, the applied fields are constantly widened. The human beings hope to let the computer solve more, more difficult problems in more and more fields. These results in the computer software scale and complexity grow day by day. So software technology faces new constantly challenge. In 1960s',the crisis of software impelled the birth of the software engineering science. Rational Unified Process is the popular engineer method nowadays, which is a currency framework, it can be used in different software systems, different application fields, different types of organization, different function ranks as well the different scale items. J2EE (Java 2 Platform Enterprise Edition J2EE) is a kind of technique framework for developing component-based multitudes enterprise applications. At present through the practice, J2EE is proved to be a reliable enterprise software developing technique. It obtains many supports of the manufacturers of IT world and owns quite wide foreground. It uses Java2 platform to predigest the developing, the dispose, the management and something correlative complicated of the enterprise-solving project. It defines a typical 4-level model, which is separated Client Layer, Web Layer, Business Logic Layer, and Enterprise Information System layer. Multitudes architecture provides good mechanism for building flexible and maintainable application system. Nowadays there are lots of government departments whose personnel administration lies in the phases of manual managing or single computer's application. And its efficiency is very low. Personnel administration is an indispensable part in the managing work of the administrative and working area. Founding tried and true personnel administration system is the necessary condition to drive the personnel administration scientific and normative. At first, this thesis generally introduces the J2EE system frame, and then combines Rational united process method to analysis and build model. Research the application of the Rational united process method in the medium-diminutive items surroundings and demands. During the practical developing process, choose and use at present the quite popular J2EE frame Struts with the items'elementary development. And achieve the essential function and general frame of the item. Struts supplied a current frame for the Web, making the developing stuffs put the concentrates into how to solve the accrual operation. Furthermore, Struts frame supplied many fields which could be enlarged and customized, making the application programs can be expediently enlarged the frame to accommodate the users'actual demands.
