The Research Of XML-based Data Exchanging In Heterogeneous Systems

With the development of cable TV, digital TV is very popular. Now cable TV Companies supply many services, such as digital TV, pay channel, video on demand, Internet and so on. How to manage the composite business is very important. The old management system cannot deal with those complicated business. Moreover, the main procedure of digital TV is business system, but there are some child systems, such as acting bank gathering, CALL CENTER, CAS, media platform, censorial platform and so on. There are no uniform information, no collaboration abilities among these child systems, also the cost of maintenance is very high. These factors effect on the development of digital TV. It's time to implement the communication and data exchange among these child systems by creating a compositive and efficient support platform.Data exchange is one of the main influencing factors of development of enterprises information. Its goal is to realize the sharing of the data in the heterogeneous environment (loose coupling, different data format, heterogeneous platform, heterogeneous area, and so on), thus utilizes resources effectively, improves the performance of the whole application system, accelerates data circulation of information system, and realizes the sharing and integration of the data. But various exchange technologies have many problems when apply to heterogeneous environments. The common question includes heavy coupling, high costs and complicated implementing. The emergence of XML has brought the new implementation method. This paper targets as data exchange based heterogeneous environment and one general heterogeneous data exchange system is designed and implemented by the technology of XML.First, various current data exchange technologies are compared,...
