Description
This paper proposes a novel framework for composing web databases. Web databases are assumed to have explicit descriptions of I/O attributes and are considered as components of functional compositions. A user writes a script to connect output channels and input channels of components. A script determines a directed graph that may contain cycles which formalizes interactive and iterative behavior of a user through a browser. The interaction and iteration are realised by the notion of CGI-link. Auxiliary filters are introduced as components for universal manipulating tools.
