摘要：Query By Example (QBE) is a database query language for relational databases. The Query By Example uses visual tables where the user enters the commands and the output is displayed in a table form. In this paper, we are proposing an automated tool where the user gives the input in the form of natural language statement (query). The tool processes the input query and retrieves the relevant matching field(s) or record(s) from the input database. The proposed tool comprises a parser where it translates the natural language statement into the tokens and retrieves the appropriate data from the database and displays the output in the form of a table. The tool takes the input from the user in the form of a natural language statement which comprises regular expression. In the proposed tool only the retrieval of data from the database is proposed which works with the print (P) command.
