数据网格技术在税务发票管理中的应用研究

税务系统发票数据电子信息分散存放在全国各个省市的服务器数据库中,数据量达到了海量数据,而各省市之间税务发票电子信息却相互隔离,在税务系统内部形成了一个个的税务发票电子信息"孤岛",对于跨地区使用的税务发票的大部分脱离了税务机关的监控;海量的发票数据信息没有得到充分的利用;社会公众缺乏统一的税务发票真假辨别平台,数据网格技术的引入给解决这一问题提供了新的解决方案。论文首先对当前阶段国内外税务系统信息化与发票管理的现状作对比,对税务发票实际管理的现状进行了分析,论述了数据网格技术在税务系统发票管理中应用的现实意义。其次,在研究了目前网格技术理论及成果的基础上,提出构建基于Globus和OGSA-DAI的税务发票网格系统(TIG)。最后论文对进行了异构数据库连接进行了模拟测试。

Research on the Application of Data Grid Technology in Tax Invoice Management

The electronic information of invoice data in tax system scatters the server database of various provinces and cities in our country,and the data is mass.However,the electronic information of invoice data among various provinces and cities is separate from each other,which forms "information island" in tax system,and it breaks away from the monitoring of the tax authorities for tax invoice which is used trans-regionally.Mass invoice data information has not been fully utilized;there are no a platform for social publics to distinguish tax invoice,and the introduction of data grid technology provides the new solutions to solve the problems.Firstly,this paper made a contrast on the current status between informatization of tax system and invoice management at home and abroad,analyzes the present situation of the actual management of tax invoice,and discusses the realistic significance for applying the data grid technology in tax invoice management.Secondly,the tax invoice grid system(TIG) is constructed based on Globus and OGSA-DAI on the basis of studying on the theory and results of current grid technology.Finally,the paper conducts simulation tests on heterogeneous database connection.
