Abstract: An extention of the QBE language in the form of graph queries is proposed for databases having complex schemata. These graph queries provide user interface for the ER model, like QBE queries provide user interface for the relational model. The implementation and usage of graph queries of ER-based “MicroPoisk” DBMS are presented.

Keywords: DBMS, database, ER-model, user interface, QBE, relational/network enterprise model
