Search-As-You-Type in Forms: Leveraging the Usability and the Functionality of Search Paradigm in Relational Databases
Querying, or searching, is one of the most important issues in relational databases. There are many search paradigms, such as Structured Query Language (SQL), keyword search, and form search, a.k.a. Query-By-Example (QBE). Among them, QBE is a good trade-off between usability and functionality. However, existing QBE systems are often inconvenient for users to compose high-quality queries quickly. In this paper the authors investigate the problem of improving the usability of form-based interfaces by enabling them to response a query in real time and tolerate the misplacing of keywords among input boxes.
