An Automated Approach for Database Queries by using DQF.

Abstract: With rapid development of scientific databases and internet information databases are becoming very huge in size and complex in nature. These databases maintain large and heterogeneous data, with large number of relations and attributes. Thus there is need of such system which generate Query Forms dynamically according to the user's need at run time. The proposed system Dynamic Query Form i.e. DQF system going to provide a solution by the query interface in large and complex databases. In proposed system, the core concept is to capture user interests throughout user interactions and to adapt the question type iteratively. Every iteration consists of 2 sorts of user interactions: Query Form Enrichment and Query Execution. In Query Form Enrichment DQF would recommend a ranked list of query form component to user so user can select desired form components into current query form. In Query Execution user fills current query form and submit query, DQF is going to show result and take feedback from user on provided query results. A user would have facility to fill the query form and submit queries to view the query result at each process. So that a query form could be dynamically run till the user satisfies with the query results.
