Key Technologies Based On The Quality Of The Data Warehouse Information Systems Research

With the development of informational process of enterprise, heavy use of Computer Aided Quality had made many data each day and accumulated a lot of history data. But in fact, these data had little use to help policy makers to make a decision and cannot meet the need of decision-making. To solve these questions is the one that enterprises must confront and figure out, especially, it's very important for many aircraft enterprises in informational process.This paper import the data warehouse which is supported technology of Decision Support System, to quality management of information, deal with mass data and resulted to decision support. The main work of this paper is study and establishes the model of quality information data warehouse, and according to the requirement of enterprise decision support carry through the development of antitype system of quality information. The paper expatiate correlation concepts of data warehouse, pay emphases on multidimensional modeling. Proceed from the theory multidimensional modeling, the paper works over the key technology of multidimensional modeling and advances some methods of modeling. Based on these academics, analyses and summarizes the system of quality information, then set up data warehouse model of quality information which is adapted to the aircraft manufacturing. With the process of data load and feedback, the quality data warehouse was steadily perfected. Finally, some work of the prototype system was done based on quality data warehouse.
