Above and beyond the years field of natural language query processing (NLQP) has seen humangous changes in research as well as methodology. Trending issue within the database management is to provide a high level interface for layman. Major source of data which is generated in many organizations and companies are stored in database which plays important role in IT field. To access these data one need to know SQL language but since layman doesn’t have any knowledge about formal language i.e. SQL a proper interface is required. So an interface for NLQP to database by using semantic grammar deals with design and developing a system which understand the natural language like English and convert English language to SQL queries. So this paper presents thee insight of NLQP system on how to enable communication between human and computers without memorization of complex commands and procedures and also NLQP system is able to intelligently process the user request in reasonable human useable format.
