....extension of the ER model, and [66, 6, 78] present a language for geoscientific applications. Among the various database languages, SQL is probably the best known approach. It is the standard language in relational database systems and has successfully been adapted for NF 2 data models (cf. HDBL [79, 80, 81] or SQL NF [82] Thereby the language has gained more orthogonality by taking into account Date s critique [83] We follow these approaches and propose an SQL like query language for our EER model. Due to the rich expressiveness, we obtain a powerful, high level, and completely orthogonal 3 ....
