Abstract

With the rapid development of computer technology, as well as the expansion of the range of applications, more and more people began to practical problems encountered in the use of computer technology to deal with life. For businesses, the most important is human resources, which is a very important part of enterprise information management, the face of a large number of personnel information, using the traditional manual approach will not only waste a lot of manpower, financial and material resources and also prone to error. In this context, the development of a to meet the business needs of the human resource management system for automated processing of corporate personnel resources is becoming increasingly important, and this is precisely the purpose and significance of the development of the system. This paper introduced the overall development process of the human resources management system, specific system developed key technology selection, system analysis, system design and system implementation can be divided into four parts. The characteristic of this system is that the introduction of Struts, Spring and Hibernate framework, has been greatly improved compared to the three combination with traditional development framework, and improve development efficiency. This paper is divided into four parts: the first part is the selection of the key technologies of the system development. First through the B / S and C / S development model comparison analysis to determine the existing Web development framework based on the B / S model development system, and then to determine the system based on SSH framework. Struts framework is introduced in order to display system and business layers were separated, so as to change the the system pages interspersed function code defects. Spring framework introduction of addition can be a good service for the intermediate layer, but also to achieve and on the compatibility between the underlayer reach the layers independently of each other the purpose, which can greatly reduce the degree of coupling between the layers. The Hibernate framework used to improve the Spring Framework JDBC package. The three frameworks technology can effectively simplify the development of the system, but also can improve system maintainability of the system performance requirements. The second part is the system analysis. First determine the necessity and feasibility of development required to achieve the basic purpose of the system as well as the development, and business needs analysis and functional requirements analysis to determine the function of the system architecture, followed by the use case diagram to determine composed of system users and the various types of users with basic operating authority of each module of the system, the final use of activity diagrams, process design and analysis. The third part of the system design. According to the business survey and analysis to determine the hierarchical model of the system, then design a timing diagram of the various features of the system, so that developers can more intuitive understanding of the workflow of each function, and then the system database system database design, first of all the way to the ER diagram conceptual design, followed by identifying the logical structure of the system database and storage solutions. Finally, since there are a lot of trade secrets in the system, the tampering of any information and will be lost to the corporate loss This article from the authentication permissions assigned three aspects of the database failure recovery and network information security system security design. The fourth part is the realization of the system. The system is based on SSH framework completed the development of the human resources management system, designed many public classes in order to improve code reuse, system time the string automatically processing class, as well as data persistent classes, based on recruitment the realization of the management module is described in detail, and the eventual realization of the basic system to meet user needs. This system is being developed on the J2EE platform out in order to achieve efficient development of the purpose of the introduction of the SSH framework, as a system back-end database and SQL Server2000 In summary, this paper describes in detail the design and implementation of the human resources management system, specific human resource management system can be divided into staff management, recruitment management, department management, payroll management, training management, attendance management, and system management of the seven major components, and system architecture solutions proposed personal insights.
