Logic programming presents better credentials than any other approach to the implementation of computer applications. In addition to providing general-purpose procedures, it is natural for defining and maintaining databases, for language processing, for knowledge representation, for parallel processing. It casually picks up numerical and combinatorial computation as special cases of constraint logic programming. Even objects that change state by interchange of messages are elegantly expressed .
Yet it was object-oriented programming that took off rather than logic programming. Why? Admittedly, during the eighties, when the crucial decisions were taken by industry and universities, not all of the strengths of logic programming were sufficiently developed. But that was only true of constraint logic programming and the lack of development in that particular branch is not the explanation.
