.... prototypes have been implemented, e.g. SALAD (see Section 2) NAIL [18] KIWI [22] or ALGRES [4] Also first attempts of combining Datalog with concepts from object oriented databases exist resulting in various deductive object oriented database system prototypes like COMPLEX [12] LLO [16] LOL [3], CLOG [13] or Quixote [34] 2 LDL LDL (Logical Data Language) was designed at MCC as purely declarative logic based language. It provides the following powerful extensions of pure Datalog (a complete presentation gives [19] C simple data types including string, integer, and real C complex ....

....in such e wey thet our methods ere not only used for deriving informerion, but elso for modifying extensionel informerion. The epproech to deductive object detebeses presented in [19] models objects with e theory grenulerity, clesses end stete evolution. However, it hes no formel sementics. In [13] we heve cerried on this epproech, relying on the sementics defined for U Detelog. However, the sementics for the lenguege hes been defined indirectly, besed on the sementics of U Detelog, following e trensformetionel epproech. In the next section we introduce e deductive object detebese system ....
