A relational database management system is presented that is tailored for engineering applications. A wide variety of enginering data types is supported and the data definition language (DDL) and data manipulation language (DML) are extended to handle matrices. The system can be used either in the stand alone mode or through a FORTRAN or PASCAL application program. The query language is of the relational calculus type and allows the user to store, retrieve, update and delete tuples from relations. The relational operations including union, intersect and differ facilitate creation of temporary relations that can be used for manipulating information in a powerful manner. Sample applications are shown to illustrate the creation of data through a FORTRAN program and data manipulation using the TEQUEL DML.
