Zusammenfassung:To alleviate the need to know the logical database organization, the authors propose the use of a semantic data model, known as the enhanced entity-relationship model, as a front-end to the relational systems. A formal, high-level visual knowledge query language (VKQL) has also been designed for this interface. This language provides for knowledge abstraction as the user communicates only domain knowledge with the system without any implication on the storage structure or search strategies. A translation algorithm is also described to translate VKQL queries to standard SQL equivalents.< >
