Abstract: Now a days the scientific databases and web databases maintain huge and different type of data. Due to the enhancement of web databases and scientific databases user is not able to get required results with the predefined static query forms. To avoid such a problem in this paper proposed the Dynamic Query Forms (DQF). In this newly defined Dynamic Query Form user can execute the query by selecting the desired form component and then he/she should submit the query for execution. At the time when user searching for the required result the system is able to catch the user interest by using the users feedback and according to that system recommend a ranked list of query form component to user. So user will be able to find the desired result as early as possible. A user can perform the form component selection and query submission operation iteratively until he/she is satisfies with the query results.

Keywords: Query Form, Query Execution, Users feedback, Dynamic Query Forms (DQF).
