Automated creation of a forms-based database query interface

Forms-based query interfaces are widely used to access databases today. The design of a forms-based interface is often a key step in the deployment of a database. Each form in such an interface is capable of expressing only a very limited range of queries. Ideally, the set of forms as a whole must be able to express all possible queries that any user may have. Creating an interface that approaches this ideal is surprisingly hard. In this paper, we seek to maximize the ability of a forms-based interface to support queries a user may ask, while bounding both the number of forms and the complexity of any one form. Given a database schema and content we present an automated technique to generate a good set of forms that meet the above desiderata. While a careful analysis of real or expected query workloads are useful in designing the interface, these query sets are often unavailable or hard to obtain prior to the database even being deployed. Hence generating a good set of forms just usin...
