Syn-construction and Synchronous Technique of Dynamic Data in Multi-heterogeneous Telecommunication Information Integration System
Deng Ming-lin · Journal of Zhengzhou University · 2007
Multi-heterogeneous telecommunication information system deals with data exchange among several databases of heterogeneous information system.In order to ensure the consistency of the data to be exchanged,it is always needed to replicate data dynamically while the data in a certain subsystem is renewed and the newly added data of the database in the subsystem should be collected to the database in heterogeneous integration system.For this purpose,several technical schemes based on the object oriented database programming technique in.NET and transparent gateway of Oracle,linked server of SQL Server are put forward.
