【摘要】 在政府的信息化建设过程中,随着业务规模的不断扩大和计算机技术的不断发展,在许多单位或部门都逐步实现了业务、信息的计算机化管理。然而由于不同时期构建的业务系统可能基于不同的操作系统和数据库平台,结果造成各系统间数据共享度极低,形成了相互隔离的“信息孤岛”。随着系统间数据共享需求的不断增加,各系统间的信息共享、互操作性就愈显得必要。因此实现系统间的信息共享和数据交换是目前急需解决的问题。可扩展标记语言XML自出现以来,就受到了业界广泛的支持并显示了广阔的发展前景。XML的作用是提供通用数据交换、变革Web发布、改造分布式计算等。正是由于XML的很多技术优势,使得它十分适合于数据交换方面的应用。本文首先介绍了XML、J2EE、Struts、Hibernate等关键技术,对数据交换的相应理论和技术进行了研究,并对XML与数据库之间的结构转换及映射,以及XML与数据库之间的数据提取与转换进行了分析设计。然后重点对数据交换平台的总体架构模型进行了分析和设计,主要包括业务层的分析与设计和表现层的分析与设计。最后依据同方股份有限公司云南分公司的实际应用实现了个人所得税代扣代缴系统与税收征管系统之间的数据交换平台。实现了从个人所得税系统导出扣款信息和查询个人所得税扣款信息功能,以及从税收征管系统导出扣缴义务人基础信息和查询扣缴义务人基础信息的功能。从实践角度证明系统框架的可行性,同时指出了系统的不足和有待提高的方面。更多还原

【Abstract】 With the development of the computer technology and the continuous expanding of the business scale, a lot of units and departments make the computerization management of the business and information come through gradually in government’s information construction process. However, due to business systems constructing on different periods may be based on different operating systems and database platforms, the result that the data sharing between the various systems is very low comes into being some "information islands". With the increasing demand of the data sharing between systems, the information sharing and the interoperability of the systems is becoming more necessary. So the realization of the information sharing and data exchange in systems is an urgent problem.XML has made great progress and been applied in the fields since it was born. It’s function is providing a general data exchange, reforming Web publishing, and transforming distributed computing. Because of the many technical advantages of XML, it is very suitable for the application of data exchange.The paper introduces XML、J2EE、Struts and Hibernate technology at first, then researches the theory and technology for data exchange, and designs the configuration transduction and mapping with the data drawing and transduction between the XML and database. Then it analyses and designs the gross framework model for data exchange platform, including the business tier and the performance tier’s analysis and design. At last it actualizes the data exchange platform between personal income tax system and tax collection and management system according to the actual application of Yunnan branch office. This system has two functions: the one is deriving and querying the deducting tax information from the personal income tax system, and the other is deriving and querying the tax payer’s base information from the tax collection and management system. The feasibility of system framework is certified in practice, and the defects and further improvement of the system are pointed out.更多还原
