Description and implementation of business logic for end-user-initiative development

The development of Web applications should be supported by business professionals since Web applications must be modified frequently based on their needs. In our recent studies utilizing the three-tier architecture of user interfaces, business logic and databases, Web applications are developed using a domain-specific application framework and visual modeling technologies. Description and implementation of business logic is a key technology. In this paper, an approach that business logic is implemented in stored procedures within database is introduced. The four basic stored procedures {select, insert, update and delete} for each table of a reuse support system are prepared. The other stored procedures are generated by modifying these basic stored procedures.
