PURPOSE: A query language window system is provided to save window resources and make an input/output of the query language possible in a CRT terminal by receiving a query language related window in an operator in an operator instruction input window directly and outputting the window through an output window without creating a query language related window additionally and to make a top/down instruction input possible by supplying a query language related exclusive graphic window. CONSTITUTION: A control mode(100) controls interactive operations of modules in a system and a data flow. A query language input/output module(110) receives a query language processing instruction from a user, displays a processing result, and supplies a query language window graphic interface. A query language processing module(120) analyzes query language stream information inputted through the query language input/output module(110) adapted to a format, reconstructs query language information, performs a sentence structure analysis and a data access to a database(200) using the reconstructed data, and transmits a processing result to the input/output module(110).
