Data Exchange Technology In The Application Of Tax Professional Management Platform

According to the information system is more and more complex now,an application syst em need more data form multiple data base to support,At the same time it also need to implem ent the data exchange between multiple application systems,How to realize the data exchange efficiently has become a prominent problem in the development of the system.With the emer gence of new system and updating from tax collection and management system of Local Taxat ion Bureau of Guizhou,it needs to upgrade part of core affairs of the tax collection system to a new professional tax management platform.Tax professional management platform at the sa me time as the province's another core application system also requires complex data exchang e with the other application systems and data exchange of high demand,high and complex en vironment.At present commonly used data exchange technology are materialized views,log mining technology(Oracle golden gate,Oracle,Stream,DSG RealSync,etc.),stored procedure combining Database link,Webservice.Stored procedure combining DBlink can realize real-time data exchange for server end-t o-end,which is suitable for the scene that data exchange capacity is not big,but is limited to o nly to realize data exchange between Homogeneous database system in Oracle database syste m;Materialized views can realize real-time/database server end-to-end timing data exchange,can have the function of incremental data/total quantity data exchange,suitable for a large qua ntity of data scenarios,but also restricted to only to realize data exchange between Homogene ous database system in Oracle database system;Using log mining technology products(Oracl e golden gate,Oracle,Stream,DSG RealSync,etc.)are all commercial software and expensiv e,and some products can only implement the data exchange between Homogeneous database system in Oracle database system,some products can realize the data exchange between heter ogeneous database systems and using data exchange technology of log mining technology can realize asynchronous data exchange,timeliness is not high.Web service can realize data exch ange between different application systems,different homogeneous/heterogeneous database s ystems.Having such characteristics that realize cross-platform and language,but the develop ment effort cost high.Through the analysis of the comparison of several data exchange technology,this paper combine with the data exchange demand in the tax professional management platform and sel ect materialized views,stored procedures,Stored procedure combining DBlink,Webservice th is three techniques as the data exchange technology of tax bureau tax professional manageme nt platform in Guizhou,and gives the specific implementation plan,test and analysis.
