....Active KDL (Knowledge Data Language) Mill90a, Pott90, Mill91, Pott91, Koch91] Active KDL which is a functional object oriented database system (FOODS) supports query driven simulation by providing access to integrated data, 2 knowledge, and model bases. Active KDL is an enhancement of KDL [Pott86, Pott87, Pott88a, Pott88b, Pott89]. The three sublanguages of Active KDL provide strong support for simulation modeling and analysis: Complex simulations may be structured using the schema definition language (SDL) results may be retrieved using the query language (QL) and models (which may include active objects) may be ....

....tasks embedded in active objects. These facilities provide a powerful mechanism for building simulation models out of pre existing model components. We designed Active KDL as an enhancement of KDL, which is a hyper semantic data modeling language developed by Potter [Pott 86, Pott 87, Pott 88a, Pott 88b, Pott 89] Recently, a partial implementation of KDL in C has been completed [Kess 89] This implementation exploits the already present data (or object) modeling capabilities of C [Duwh 89, Lipp 89, Berr 88, Wein 88, Stro 86] KDL schema and queries are translated (via yacc) to C , at which ....

....base capable of advising students [Pott88a] Integrating the three foundation areas via Active KDL is the focus of our work (and has been since the mid 1980 s) and represents the primary difference between Active KDL and other object oriented database systems. The underlying foundation of KDL [Pott87, Pott88b] as well as Active KDL [Mill90, Mill91a, Mill91c, Pott90] is the hyper semantic data model KDM (Knowledge Data Model) Pott86, Pott88b, Pott89] Hyper semantic data models provide extensive modeling capabilities that include those of standard semantic data models and object oriented data models ....
