Research On The Model Of The Large Centralized System Of Tax Data In The Province

The taxation information system after ten years of rapid development, thetax system more comprehensive coverage of business, data concentration is alsorising, the rapid growth ofdata quantity and precipitation, how to make use of and make good use of these valuable resources has become an important task faced by tax department. Highlight the "people-oriented" design concept, to expand the sources of revenue management as the center,two basic directions, one is to the taxpayer as the center, activity and process for the taxpayer, taxpayer perspective to organize data, fully support the tax service. The two is totax staff asthe center, facing the internal management, from the perspective of taxpersonnel to organize data, the full support of the internal management activities. In the use of all kinds of explicit knowledge and tacit knowledge data, discovering rules behind the data summary more, after the tax system for big data applications, and lay a goodfoundation for the sustainable development of the information and data. This paper mainly through the construction of provincial comprehensive data summary and elaboration onthe implementation of the information management tax, how to promote value-addedapplication data source control.The level of classification and summarizes the first business tax system running business,and summarizes the formation of stable with respect to theoretical guidance, is mainly used for later classification application level, and business application scenarios. According to the characteristics of the industry, finishing business data accumulated at present taxsystem, and its distribution and storage business, as well as the focus of construction field,establish the data model for thenext step of the conceptual model design. According to the design model, and the classification of data items and divided into data model, according to the coverage of business data model to enhance business links,enrich and perfect the tax system. Division of physical layer in the implementation process,the life cycle, the data level data. At the same time, clear data constraints and planning,implementation of data loading strategy to make full use of computer hardware, database optimization, replication strategy, speed and stable data model.Make full use of the data information technology combined with the strength of ourinformation to rely on information technology as a means to the tax related business to focus on revenue, information exchange, tax source management, law enforcementservices, collection efficiency, performance evaluation, dataanalysis as the breakthrough point, identify the location, to seize the key link, data application platform to form a largecentralized model integration operation and display.Combined with the application environments and scenarios, in view of application for different levels of users selected data application forms, the output uniform caliber data,output data of the unified rules, to enhance the user experience. In the organization of data in the US, the macro and micro angle, three kinds of organization function, realizes the data output data caliber rule of standardization, integration, so that all in a business domain query caliber unified standards, focus on "risk management" concept, combined with the business aspects of coherence and all the query function is to reflect themanagement level, to eliminate the previous "data roaming" no purpose query.In application mode, the "four" the application demand, namely: provinciallevel, branch,branch management, give full consideration to a query function of industry boundaries,according to the user’s position, different functions, positioning the relationship between supply and demand and data access between the maximum balance, unity to show the wayto realize the information and display strateg y, achieve the user experience on the simple,changeable, in the management way in the application effect of unified model.In the operation in the form of user experience to ensure that the premise of the speed of query, query format unified style and output interface, we use the surface, combined with the query, to avoid a large number of complex combined the original query, push mode of operation is based on the summary of the data to guide. The first form of exhibition,gradually layer by layer to analyze thequery results, making all kinds of combination ofqueries, query results and are integrated in the process, until the user access to thedetails of specific data information. Query function to "tell" thinking tool, multi angle display data information data. Users within the scope of the self organization, query results, give full play to the initiative of the staff.
