Design And Implementation Of Query And Analysis System In City Taxation Administration Bureau

Along with the fast development of information technology, nowadays, its applications also extend to tremendously vast domains. In real and concrete business environment, how to make good use of these technologies and facilitate the traditional business to a better prospect, thus make a better effect, is an urgent and pressing work for taxation administration bureaus to accomplish with respect to the work of taxation informationation. This thesis pays great attention to the theories concerning with data warehouse and J2EE technology, and based on which, gives a prototype data warehouse system applied to one city-level taxation administration business, furthermore, an up-to-run data query system is established according to this model.Main features of this thesis:1. Implements every step of the modeling procedures required by a data warehouse project, and makes a primary study of data warehousing in a real circumstance of taxation administration bureau.2. In order to break one of the "bottlenecks", namely the data quality that hoops the application of a data warehouse, this thesis makes a significant focus on the data integration. Based on the considerate analysis to a real word transaction data of a taxation administration bureau, the dependency diagram of the data objects, as well as the customized data extracting method is determined. The data extraction, data transformation is automatically applied by a scheduled and incremental technology which guarantees the high quality of the data, and an incrementally reconstructing strategy is proposed.3. Play an important role in application-layer analyzing, namely the requirement analyzing. A good application needs a complete, well-structured requirement. Data warehouse application system is a recycling and never ending procedure, therefore if an information system is to become mature and up-rising round above a round, the only perpetual impetus is: requirement.
