A Web Based Tool for Accessing Distributed Relational Databases through Multilingual Fuzzy Interface

Most of the relational database systems use SQL, which has strict syntax and semantics defined precisely to retrieve data. Sometimes, user may not be aware of SQL syntax and concepts and wants to use databases without any technical effort. In recent years, an increasing number of people have begun to realize the need for a technology to reach beyond the barriers of SQL. Some of papers have given solutions regarding this problem in 1999 [1, 3]. We have developed a fuzzy query system for multiple human languages. The implementation is an interface between the user on the web and the databases spread over distributed database servers. It gives the flexibility to query the database in any natural language. It provides a facility to make a fuzzy query and it also corrects wrongly spelled words in the query. If the query is in natural language, the system parses it and converts it into SQL after resolving various tables, attributes and fuzzy terms used in the query. The system also accepts SQL query straightway. The interface is generic enough to work on all Relational Databases and is a generalized tool which can be customized for any organization and any natural language. Thus its use has reduced a need of trained professionals in organizations.
