Integrated Iron And Steel Enterprises Heterogeneous Systems Based On Xml Technology Research And Application

For corporations, the corporate mergers and acquisitions, employee turnover and policy changes, as well as many other reasons: for example, enterprises have a system set up with different languages, the software running on different platforms, different hardware etc... The possession of large scale system which is different from each other is very common, and unified system is very rare. With the rapid development of information technology and competition among enterprises is becoming increasingly intense, many factors have contributed to people's higher demand to information systems, and this is the needs of internal development of enterprises and also the adaptability to the external environment. Hence, to be able to share or integrate each other's different information, more flexible and open information systems of enterprise is desired. However, the information system's structure and the structure of data sources are different, so that these systems' data exchange and integration encounter obstacles. And all of this make the integration of enterprise heterogeneous data into the current construction of the enterprise information hot and difficult one.To this end, this paper associate Kunming Iron and Steel Group information project" Kunming Iron and Steel Group 's mechanical properties testing system for products " and " Kunming Iron and Steel Group QS system" previously had been on the line ,studying some heterogeneous technologies which is suitable for the enterprise, and realizing the sharing, exchange and integration of heterogeneous data with Some of these technology, that is, describes the data in different data sources in a unified data model, shielding the heterogeneity of platform, data structure etc., realizing seamless integration of data.In this paper, around the goal of integration of heterogeneous systems, after studying the subject in-depth, collecting and collating information literature, we put forward an integration system design framework which is based on XML technology with the middleware thinking and the combination of Web Service and Socket Monitoring in the optimal principle. In the system ,message middleware adopt XML,ADO.NET, transaction processing middleware adopt Web Service and Socket Monitoring, WEB application server middleware adopt JBOSS and IIS, data access middleware adopt JDBC. Choosing such a framework is because building a system that based on middleware thinking has many advantages, such as scalability, the great ability to resolve complex issues, short development cycle, low-risk and so on. And the rapid development of XML in recent years with the advantages likes self-definition, scalability, easy description to various types of data etc... And this makes it a suitable language to descript heterogeneous data, solve the data interface issue and realize the integration of heterogeneous data.System design and implementation fully taken into account the various actual situation in the enterprises, In addition to satisfying the basic functional requirements, the building of the system is guaranteed to the maximum extent possible versatility, flexibility, security and robustness, etc.. Uncertain factors such as the test items change or new products appear, systems have good versatility and scalability, in such cases, the system is no longer required hard-coded, but only through the configuration of the system configuration that can run; and If anomalies in the network, the system provides a minimum operating mode, which can guarantee the normal production and make the system good robustness. At present it is in trial operation, its research and realization can not only provide iron and steel enterprises in the construction of integrated information systems for reference, in other manufacturing industries which also has practical significance and value.
