dc.description.abstract This thesis effort developed a user-oriented query language interface, patterned after IBM's Query-by-Example, for the Mistress relational database. The interface, Mistress/QBE, is written entirely in C and uses the UNIX curses library of subroutines to allow full screen input and output. Mistress /QBE allows the user to issue commands to draw pictorial representations of tables which exist in the database. The user then enters values and operators into the tables to specify a query by indicating attributes to be used in conditional selections, sort and grouping orders, and output formats. Mistress /QBE decodes the information entered on the screen and formulates a Mistress Query Language command which is passed to the Mistress standard C language interface for execution. With a few minor exceptions, any query which can be written in the Mistress Query language can also be written in Mistress/QBE. The interface also includes a high-level operator- called grouping, which is supported by IBM's QBE but not by native Mistress.
