基于多层结构体系的人力资源管理系统
|
摘要
人力资源管理系统是企业管理系统的重要组成部分。目前部分企业人力资源管理方法陈旧,工作效率低下,导致了企业人力资源管理难度加大,管理成本居高不下。因此,提高企业人力资源管理的电子化信息集成水平,对提高企业的整体管理水平及经济效益具有很大的现实意义。
随着面向对象技术与分布式技术的发展,应用系统相应的被要求在不同平台的运用和集成能面对更高的复杂性和高可用性。因此企业对应用系统的设计提出了更高的要求,即更好的安全性、更广的适应性、更大的伸缩性以及更便利的维护性。本文对现有的分布式对象技术、分层体系结构进行了详细的介绍和比较,对CORBA技术的最新发展以及与其它主流分布式技术进行了比较,说明了利用CORBA技术构建分布式应用系统的优势所在。
以分布式对象计算的特点、分层体系结构概念、面向对象技术以及CORBA规范为技术背景,本文探讨了一种多层分布式应用系统的开发方法。这种开发方法基于PowerBuilder面向对象的开发工具,结合Jaguar组件事务服务器和多层客户/服务器与浏览器/服务器体系结构的优势,把应用系统核心看作一组各种服务的集合,每个服务由分布在物理上不同地方的多个组件组成,使整个应用系统具有易集成、易伸缩、面向多用户、广域性等特点。并以云南华能澜沧江水电有限公司人力资源管理系统为例给出了具体的系统分析和系统实现。对两层结构的系统移植到三层以上体系结构给出了详细的解决方案。
Human Resource Management System(HRMS) is a vital part of management system. At present, some of the enterprises’HR management systems are outdated and inefficient, which leads to extreme difficulty in HR management and expensive costs. Therefore it is necessary and important for enterprises to improve the electronic integrated level of HR management to improve their information level and economical benefits.
With the development of the object-oriented technology and distributed computing the application and integration that the system is required to be put in the different platforms can be faced with the much more complexity and higher feasibility. As a result, enterprises demand the application system of higher standards in design such as better security, broader adaptability, better feasibility and more convenient maintenance. Detailed introduction and analysis about the present distributed object technology and multi-layer architecture is presented in this article with comparison between the advanced development of CORBA technology and other main distributed technology, which shows the advantage of developing distributed system using CORBA.
Based on the characteristic of distributed calculation, the conception of multi-layer architecture, object-oriented technology and the technical background of CORBA specification, a method of multi-layer distributed application system is discussed in this article. With the object-oriented development tool PowerBuilder, by combining the advantages of Jaguar Server and C/S and B/S architecture, the core of application system is regarded as an integration of all kinds of service and every kind of service is consisted of many components distributed in physically different places and may multi-used by required application, which makes the whole system characterized by more integrated, more flexible, facing multi-users, broader extension. Detailed system analysis and system realization for the HRMS of Yunnan Huaneng Lancang River Hydropower Co.Ltd. is presented in this article. An elaborate project for transforming the C/S system architecture into multi-layer system is also presented.
