Visual Database Query Language

Abstract

Structure Query Language (SQL) is the most widely used query language in the modem relational database management system (DBMS). Its use is straightforward for simple queries, but it gets complicated, hard to comprehend and express for the complex queries. In term of easy of use, Data Flow Query Language (DFQL) represents graphical user interface to the relational model based on a dataflow diagram, and retains all the power of SQL and is equipped with an easy to use facility for extending the language. With Java's flexibility and power, it is possible to build such system that allows the users to login any relational database through JDBC, graphically view the database structure, and implement the DFQL to query the data from the database. The design recommendations and implementation of a prototype are the primary research areas of this thesis.
