Application Of The WEB Services In Professional Tax Sources Management Platform Of Guizhou Province

With the time going by,the informationization degree is becoming higher and higher,and various kinds of application systems with many features are becoming the right hands in our daily life.In some industry with higher informationization degree,a unit always owns multiple application systems which form its complicated systems.Because of the business requirements,the data in these application systems are always intersected with each other,but they are maybe developed at diverse platforms with different languages.Thus,one difficult problem lies in how to fluently do the business flow and data interaction among those application systems.Besides,it is also a challenge to keep data safe when the data interaction happens among multiple systems.Several industries require higher level of dada safety own to the particularity of these industries.When developing the platform of professional management of tax sources for Guizhou province,the similar problem occurs.As an important application in Guizhou tax information system,the platform of professional management of tax sources needs to intersect data with many other application systems,among which the production base of Guizhou province is the database including the whole data of tax sources in the province,so the absolute security of the data in production base must be greatly ensured while connecting the platform with the production base,and the data in production base cannot be directly exposed and optionally operated by other application systems without limits.In view of the above factors,this platform gives up the data synchronism technology,such as materialized view,flow replication,stored procedure,which are frequently employed before.Its data manipulation SQL is encapsulated as the stored procedure in the production base.Tax professional users are endowed with the right to carry out the stored procedure through the authority management of the data base.And the stored procedure is encapsulated as Web Service in the platform.Net,and its interface is used by the platform of Professional management of tax sources,which can avoid the direct operation of the data in production base.Additionally,the reversed interface is deployed in the production base,which is out of the consideration of the potential demand of its intersection with other application systems in the future.As a technology programming language cross platforms,Web Service makes it easy to use this interface when other application systems need intersect data with this production base.On the basis of ensuring the data security,the employ of Web Service not only successfully solves the problem of reversing the data of the platform of professional management of tax sources to the production base,but also reserves the interface for the future application systems.After one year' s trail-operation,this system meets with success,and the provincial Tax Bureau decides to expand it to the nine states of Guizhou province.
