Abstract

We consider the following problem: For a system consisting of two submodules, the behavior of one submodule is known as well as the desired behavior S of the global system. What should be the behavior of the second submodule such that the behavior of the composition of the two submodules conforms to S? - Solutions to this problem have been described in the context of various specification formalisms and various conformance relations. Here we present a generalization of this problem and its solution in the context of relational databases, and show that this general solution can be used to derive several of the known algorithms that solve the problem in the context of regular behavior specifications based on finite state automata with synchronous communication or interleaving semantics. The paper also provides a new solution formula for the case that the module behaviors are specified in a hypothesis-guarantee paradigm distinguishing between input and output. A new submodule construction algorithm for synchronous, partially defined input/output automata is also given.
