Design and Implementation of Human Resource Management System based on ExtJS and J2EE

摘要

The most fundamental reason for the human resources management system is the optimization and utilization of human resources management system, to obtain the best economic benefits. Now the concept of people-oriented, human capital is far more important than the land, plant, equipment and funds, etc. You want to shine in the computer science and the application of human resource application, it must be human resource management properly, can play the best utility of human resources. With the rapid popularization and development of information technology, how to improve the management level and production efficiency of enterprises by using information technology is more and more important. As an important management information system in the enterprise, the human resource management system is very important to the enterprise production and management. In order to adapt to the economic development, improve the market competitiveness of enterprises, we must establish a set of reasonable and efficient human resources management information system, will change the original manual management inefficient for the use of the computer automation management, not only helps to reduce the duplication of work, improve the production efficiency, but also improve the management level and the ability to optimize the allocation of human resources of enterprises. Based on the enterprise application as a starting point, firstly, the basic concepts and research the human resource management system of the relevant characteristics and the current development situation, expounds the significance and necessity of the development of human resource management system based on J2EE mode. Secondly, this paper presents the design and implementation of a J2EE based hierarchical architecture and MVC model of human resource management system, to build a Spring based, Hibernate supplemented by the application framework. In this paper, on the basis of the SSH framework, combined with the three characteristics of the development and application of J2EE system based on configuration, multi user efficiency and scalability, in the aspect of technology are given the system data layer, business logic layer, system layer is the Web layer system show the corresponding design scheme. System in the design using Hibernate technology to avoid the direct operation of the database and the realization of the data resources of the package. The use of Struts architecture to make the component in different business logic layer of the association between very few, low coupling, greatly improved the application of maintainability and scalability. The system has been tested to meet the requirements of the design, put into use will greatly reduce office consumption, improve office efficiency. And use the user experience better ExtJS to make up for the lack of SSH framework in the presentation layer. This topic is in the Java development environment, MyEclipse as the development tool, SQL Server 2008 as the database of the system, through the Tomcat server, using B/S three layer architecture, the system has good maintainability and reusability. At the same time, in the process of software development, the use of MVC design patterns and object-oriented design and development methods, easy system design and implementation. In this paper, the development and implementation of human resource management information system are described in detail in the following aspects, such as requirement analysis, system design, development environment configuration, system implementation and so on.
