Application and Research of Dynamic Multidimensional Data Modeling in Government Statistical Management Information System

摘要

As the requirements of Statistics Department constantly adjust,great changes will be taken place on data structure of statistical management information system (MIS). Thus the government statistical management information system must be able to change the structure of the data dynamically,and data modeling for statistical database correspondingly became more difficult The requirement of analyzing statistical data in multidimensional way is also becoming more and more important. Multidimensional modeling is a data modeling method which is normally used in the process of data warehouse building. Since statistical data have the same important characters as data warehouse: multidimensional and time dependent,so this paper proposes a method of dynamic multidimensional data modeling in government statistical management information (MIS) to solve the former problem,and it would be helpful for analyzing multidimensional statistical data.
