Senior Data Warehouse Based Management Information System

In the earlier period, large enterprise developed its management reports system based on files system and the 3rd-generation language. The managers of several departments access management information from the reports system. Because competition stress increases quickly and information requirement changing frequently, the legacy system could not satisfy the information need of managers. The maintain ability of legacy system is decreasing, and the cost is growing up.This research is to propose a data warehouse structured EIS. The research combines the On-line Analytical Processing (OLAP) and web page techniques, then using the data given by the higher executive of the manager; it applies a prototype to create awed-based pivot-analysis EIS. The company's higher executive can use the browser to search on thyself-management factors. If an abnormality is detected, the pivot analysis can be used to conduct multi-dimensional analysis to find the reason for the abnormality. This research not only provides EIS database access and method for creating the system creation it also shows the relationship between the EIS and the data warehouse.
