Size estimation of multidimensional views of data warehouse is a fundamental step for data cube design, warehouse storage planning, and query optimization.

This paper describes an efficient method of developing multi dimensional cost views to support enterprise s multi dimensional cost analysis by incorporating the knowledge activity based on costing and OLAP technology.

The algorithm technique of dress recognition of model posture based on the three dimensions view is put out in this paper.

According to the purposes and requirements of applied undergraduate education, the progressive reform is carried out in Engineering Drawing course to form the idea of "view thinking", to adopt the blended teaching mode of modular combination of engineering drawing and AutoCAD, and to introduce the idea of integrated courseware to develop MCAI courseware by network technology.
