The Multi-Dimensional Data Analysis' Design And Realization In The Principal Decision-making Supporting System

In the past dozens of years,with the development of the computer and information technology,the development and construction of the data analysis and the decision support system is integrated into the information construction process.In the university,a large number of different formats of data storage have been accumulated in teaching management information system.Since the information structure is complex and the quantity is extremely huge,it will be so significant to discover the latent nile and the valuable information from how to realize multidimensions and multi-level analyses of these information,and then to realize scientifically the decision support.The main topic of this research is multi-dimensional data analysis technique,including data analysis algorithm and on this basis,building a multi-dimensional data analysis system and scientific and effective analysis of data for teaching management.And,in turn,it will be applied to promote the teaching management of scientific,regulatory and efficiency.Depending on the long-term accumulated data of Beijing Polytechnic College educational administration information management system,on the base of researching current common multi-dimensional data analysis technology,the project quotes the current popular soft algorithm method-rough collection algorithm into the multi-dimensional data analysis.And multi-dimensional data analysis system based on the educational administration system has been utilized successfully for the university scientific style teaching management,which confirmed the usability of the algorithm.The main task of the article includes:1.Researching and analyzing to the data warehouse technology carefully2.Studying online analyzing to the process the(OLAP) technology thoroughly and has given the model realization method and the good and bad points.3.Researching one new soft computational method:the rough collection method,and applying the rough collection attribute reduction algorithm into the data analysis of the educational administration system.Developing the rough collection application scope,enhanced multi-dimensional data analysis highly effective.4.Based on several research foundations in above,through the construction multidimensional data analysis system model,designed and realized algorithm designing and coding of system administration module of the educational administration management system,the student result module,the employment analysis module and the quality of teaching module and through testing,finally completed the multi-dimensional data analysis system development. Verify the algorithm usability and simultaneously made the contribution for the teaching management.
