Application research on software reuse technology

Software reuse is one sort of computer software engineering theory and technique. The paper designs the .NET framework-based software reuse technology. In User Interface Layer it makes full use of many widgets and labels to reuse codes and to recompile pages; in Business Logic Layer it adopts Web Service to achieve internet-based distributed coupling; in Business Component Layer, it adopts object-oriented system design to provide independent and extensible shared business interface and data structure; in Data Access Layer it takes advantages of XML data integration to provide XML interface for data accessing. It can access and output database of any platform with the assist of XML standard structure to finally fix the reusability problem of the traditional software in Business Logic Layer and Business Component Layer.
