It has been widely observed that temporal semantics and functionality are often developed on an ad hoc basis, and the benefits of temporal database research are rarely realised. The object-oriented paradigm offers many in terms of performance, semantic richness, and re-use; these advantages can be realised as conceptual and software components known as business objects. However, fundamental barriers to the use of temporal database research in real business software remain. These barriers. namely the absence of a consensus temproal object model and the lack of suitable temporal modelling tools, are addressed in this paper. Unless these issues are addiressed, the development of re-usable temporal business objects will not yield tangible benefits in commercial environments.
