基于XML的数据交换平台及其关键问题的分析与设计
|
摘要
目前,信息技术、网络技术发展迅速,但企业和政府部门在以往开发信息系统时缺乏统一的部署,异构问题的因此日益严重,数据交换困难,形成了信息孤岛问题。在信息化的趋势下,迫切需要各个企业及其下属各个部门的信息能够及时获取和共享。数据交换平台方案是解决此问题的有效方式,通过它可以在一定程度上保护企业原有信息建设投资,又延续了一直以来对系统的使用习惯,更重要的是缩短了系统开发周期,使各系统的数据得到了交换,达到了信息共享的目的。
本文的研究来源于某科技厅的数据交换平台建设的项目。论文首先通过对该项目的研究和分析,提出利用XML技术为基础的数据集成解决方案,设计一个能在异构系统之间有效共享和通用的数据交换平台架构,满足了科技厅的数据交换平台建设的需求。然后在分析这个数据交换平台架构和数据集成的过程,指出影响交换平台实现的三个关键问题:数据标准制定、数据交换实现和平台安全性,然后对这些问题进行详细的分析和设计。
论文在研究数据标准制定的过程中,对科技厅中的各个系统进行了详细的调研,特别是对各个系统的数据资源进行了细致分析,遵循有规律和易于扩充的原则,并在此基础上设计的共享数据规范。这样,从各个子系统中提取出来的共享数据都要转换成此格式以方便共享。
数据交换利用XML及相关技术,实现业务系统异构数据到平台中间数据库的转换,这是整个系统数据集成的关键。论文重点描述了这个过程,首先从各个子系统数据库中抽取得到的共享数据首先根据定义好的文档格式,转换成符合共享数据规范的XML数据文档和Schema映射文件,最后传输至中间数据库端,并在那里被再次转换成数据库中的数据。
论文对系统安全性进行分析,详细考虑了系统访问控制机制,对敏感的并信息进行WS-安全性设计,然后设计了一个数据安全过滤接口,实现对一些恶意信息的过滤,以此来保障了系统的安全。
总之,本文分析与设计的数据交换平台基于XML技术建立起来的,可以方便以后系统的维护、扩展和改造。同时又充分考虑了系统的安全性问题,为在网络环境下的数据共享提供了安全可靠高效的保障。
With rapid development of information and network technology, the situation of heterogeneous is more and more critically in the enterprise and government. Because their information management systems is lack of unified deployment when they are developed. It is an urgent need for all enterprises and their subordinate departments to make timely information access and sharing in the trend of IT application. The scheme of data exchange platform is effective pattern to solve this problem. It can be protected the investment of original information system and continued the used habit of the system. More important, it can be shorted the development cycle, exchanged data, and sharing information.
This paper originates from the project of data exchange platform in science and technology center. Through the research and analysis, I designed a solution for data integration base on XML. It meets the needs of data exchange platform. It can be pointed out three key problem in the process of implement to analysis this architecture and the process of integration first, and then analysis and design these problems. There are the formulation of data standard, the implement of data exchange and the security of the platform.
The data standardized is designed by the detail investigation to the various systems of science and technology center, particularly in its data resources. And it is designed by following the laws and principle which is easy to expanse. The sharing data which extract from the subsystem was transform to this format in order to share it conveniently.
Data exchange is using XML and its related technology to implement the data exchange from the business systems to central database. It is the key of the data integration of the whole system. The various subsystems can send message to middle database. It is defined a document format firstly, and use templates to convert into the XML data document and Schema mapping file, and transmit it to the central database.
The security of the system is an essential part in the process of the implement. The paper considers access control mechanisms of the system in detail, and then designs WS-security to sensitive information. It also designs a security filter data interface and malicious information filtering to protect the security of the system.
In short, the data exchange platform is build based on XML. It is facilitate to maintenance, expansion and transformation of the system in the future. It also made full consideration to the security issue for system, and provides a safe, reliable and efficient protection to sharing of data in the network environment.
