Hanslip E-mail: dch@aeg.dsto.oz.au Michael Jackson's JSD (book/method) covers this, though many would dispute that JSD produces an OOD. The only reference I have is for his book, which is getting on a bit now: "Jackson: System Development" (dunno the ISBN). I think it's a good book for OOD, even if one doesn't think it is quite "right". I do have a self-produced "distallation" of JSD I could send you/anyone who is interested (it's ~50Kb uncompressed and uses nroff & mm macros). ------------------------------------------------------------------------------- Matt Atterbury [matt@bacchus.esa.oz.au] Expert Solutions Australia, Melbourne UUCP: ...!uunet!munnari!matt@bacchus.esa.oz.au "klaatu barada nikto" ARPA: matt%bacchus.esa.oz.AU@uunet.UU.NET "life? don't talk to me about life!" -- ------------------------------------------------------------------------------- Matt Atterbury [matt@bacchus.esa.oz.au] Expert Solutions Australia, Melbourne UUCP: ...!uunet!munnari!matt@bacchus.esa.oz.au "klaatu barada nikto" ARPA: matt%bacchus.esa.oz.AU@uunet.UU.NET "life? don't talk to me about life!"

In applying OOA and OOD to a simulation problem to be hosted on multiple Sparcstations using C++, it has become apparent that the transition from OOD to processes and subsequent OOP is a major conceptual hurdle. The problem apparently is the differing levels of abstraction. To this I would add the lack of graphical design aids. The few references I have seen solve the implementation problem using OOPs with concurrent features or extensions to existing OOPs. Can anybody provide references that may be helpful? Thanks.

One reference to concurrent design in object-oriented systems is the Object-Oriented Concurrent Systems tutorial in OOPSLA '89. You might also check references on Actors. It has always seemed to me that once you have defined your objects and the interactions between them, concurrency design is achieved by partitioning the objects into processes. The interactions between processes are then visible, and technology can be selected for achieving the communication based on the nature of the interactions. I havn't seen any good treatment of response time analysis for such a design, but there is a reference to this in the March 1990 article by Berzins and Luqi in IEEE Software. I suspect that you'd need to build a simulation to make sure that you've made a good choice. Bob Fraley
