ABSTRACT:
An inference engine in a knowledge base system may be invoked by an application program (e.g., a COBOL program), by arranging to detect, in the program, instructions whose syntax complies with the syntax requirements of a predefined data base manipulation language (e.g., SQL), and then executing the instruction by invoking the inference engine. As a result, the application programmer can implicitly and transparently take full advantage of the facilities of the inference engine using simple, known data base manipulation language statements. In other aspects, the "if (condition)" side of an inference rule triggers the inference engine to execute a sequence of steps based on a class of facts referred to in the condition and based on prestored information identifying the storage scheme for that class of facts; facts retrieved from an external data base are filtered to eliminate unneeded facts, before transducing the remaining, needed facts into the temporary storage space; and the knowledge base system exercises control of the cursor control mechanism of an external data base in order to retrieve facts one by one as needed by the inference engine.
