Towards a Unified Query-by-Example (UQBE): UML as a Basis for a Generic Graphical Query Language
A generic graphical query language for ODMG-compliant object databases is proposed, based on the ideas of Query-By-Example, and using UML-like diagrams as schema notation. Ease of learning for users coming from the relational world and support for non object-oriented data sources are also considered as design goals. The overall layout of the query language is described, illustrating its potential expressive power via ODMG OQL comparisons. Keywords. QBE, graphical query language, ODMG OQL, object database queries, UML.
