In this paper, through the research of the existing computer assisted instruction system, based on the detailed analysis of its functional requirements, object-oriented software engineering approach is used for full-scale system design, which makes the analysis process and development process more closely combined. A general framework which is clearer, easy to develop and practical is also proposed...
The slewing rings enterprises in China have relatively stable product categories at present, and their daily process design mode is the modified design based on the base type products, so they urgently need an efficient and practical slewing rings CAPP system. Based on function requirements analysis, this paper developed a practical retrieval slewing rings CAPP system with object-oriented method,...
