Civil Servants Management System Based On Windows DNA

In computer science and technology rapid development today, people from all walks of life on the application of an increasingly large software system requirements, the importance of software to the user is rising, using layered technology can reduce software development in the process of developing the many repeated work, improve the efficiency of software development, curtail costs, and it can reduce the development period. So the technology has been widely used.This paper introduces the background of the research and development issues, and then layered structure of the development of the technology were summarized. Then we discuss the field engineering, ECC, object/mapping relationship related object-oriented technology, especially Windows DNA,and we also explain the use of technical architecture of the system development stratification in each layer of the sublayer, and the relationship between using stratified technology designed official information management system in this paper.In This paper we explore the method,of how to use stratification technology in the development official information management system,, with the system of the information acquisition, storage, classification, arrangement, after deep operation the system provide information to decision support, has the good interface, can be quickly and easily finding the informations, grasping the unusual situation of employees. the personnal department personnel to post, ascension, training, retired are provided complete and scientific theoriesOfficial information management system use Windows DNA technology, the presentation layer, business appearance layer, business logic layer, data access layer, data layer of five layers framework. The first layer is human-computer interaction. The second layer packages the appearance of the basic flow, to give the first layer provides a simple interface. The third business logic layer contains entity object of the basic code, and other objects to code for the foundation. above the third layer there is a data access layer, the layer package database of all kinds of operation with 0 / R Mapping technology to, all sorts of database software has unified interface, improve the system of portability. Final layer is data layer, this layer is toally include the data of all the system.Finally we discuss the object-oriented and the Design patterns in each layer,and introduce the work flow of the system. The Advantages and disadvantages of the system are pointed. We complete the base of the next step.
