Query form is one of the most widely used user interfaces for querying databases. Traditional query forms are designed and pre-defined by developers or DBA in various information management systems. By this rapid development of web information and scientific databases, modern databases become very large and complex. Therefore, it is difficult to design a set of static query forms to satisfy various ad-hoc database queries on those complex databases. Dynamic queries are a novel approach to information seeking that may enable users to cope with information overload. They allow users to see an overview of the database, rapidly explore and conveniently filter out unwanted information. Users fly through information spaces by incrementally adjusting a query (with sliders, buttons, and other filters) while continuously viewing the changing results. This paper proposes Dynamic Query form, a curious database query form interface, which is able to dynamically create query forms. The significance of DQF is to capture a user’s choice and classify query form components, support him/her to make conclusion. The creation of query form is a repetitive process and is conducted by the users. In each repetition, the system automatically creates classification lists of form components and the user then adds the desired form components into the query form. The classification of form components is based on the captured user choice. A user may al so fill up the query form and deliver queries to view the query output at each step. Thus, a query form could be dynamically refined till the user answer with the query output. A probabilistic model is developed for estimating the excellence of a query form in DQF. I have studied evaluation and user study certify the effectiveness and efficiency of the system.
