Apparatus and methods which employ a machine learning system to "learn" the specification for a program from a trace of an execution of the program on a set of test problems. The program is instrumented to produce the trace. Performance is improved by means of a declarative bias which expresses knowledge of the user about the program and constrains the learning system to produce only specifications which are consistent with the declarative bias. The apparatus and methods of thepreferred embodiment are employed to learn specifications of views in a data base for a telephone switching system from traces produced by executing the programs which produce the views. Techniques for producing more than one specification and for dealing with views which involve conversions are also disclosed.
