Abstract
INTER-Mediator is a framework for developing web applications. Mainly it can be applied to the business system for small and medium organizations, especially limited budget circumstances. As far as presenting and updating the data of database, we can build the page with the declarative way, not any imperative ways by programming languages. This means end users and designers can maintain the developed system, for example adding page elements. In this paper, we discuss how does the framework work and describe the some maintenance tasks can work out by using the declarative way.
