The development of Web applications should be supported by business professionals themselves since Web applications must be modified frequently based on their needs. In our studies with the three-tier architecture of the user interface, business logic and database, the construction of the graphical user interface and the simple database system was supported by using a domain-specific application framework and visual modeling technologies. The conceptual model is based on CRUD (create, read, update, and delete) operations. As for the business logic, however, it is rather difficult to support it by the same method because there are various kinds of business logic. This research proposed the ABC model: application = business logic + CRUD. This model was applied to Web applications in practical use with case studies. Finally it was confirmed that the development process based on the ABC model was useful for an end-user-initiative approach.
