Integrating databases, search engines and web applications

Abstract

This paper addresses conceptual modeling and automatic code generation for search engine integration with data intensive Web applications. We have analyzed the similarities (and differences) between IR and database systems to extend an existing domain specific language for data-driven Web applications. The extended Web modeling language specifies the search engine's index schemas based on the data schema of the Web application and uniquely designs the interaction between the database, the Web application, the search engine and users. We also provide an implementation of a CASE tool extension for visual modeling and code generation. Experimentation of the proposed approach has been successfully applied in the context of the COOPER project.
