Modern scientific databases and web databases maintain large and heterogeneous data. These real world databases contain over hundreds or even thousands of relations and attributes. Traditional predefined query forms are not able to satisfy various ad-hoc queries from users on those databases. This paper proposes DQF, a novel database query form interface, which is able to dynamically generate query forms. The essence of DQF is to capture a user's preference and rank query form components, assisting them to make decisions. The generation of a query form is an iterative process and is guided by the user.
