Iterative Querying in Web-Based Database Application

Abstract

Web applications are increasingly relying on databases. The traditional method offered by most web sites of submitting a query across the Internet and getting a response from a server packed in a Hyper Text Markup Language page is no longer satisfying [1][3][4][5]. This is due to the result set: it is often too large or empty. This forces the user to try and guess which constraints should be relaxed or tightened in order to obtain the desired result set. And so, the user goes through several submit/response cycles. Web applications that require this sort of interactive exploration of databases need to use a model that is different from the submit/respond model described above. In this work, we propose an iterative querying model that integrates querying with result browsing.
