This weeks panel presented a very interesting look at model driven development, specifically, what some of the issues associated with it are, and why it hasnt had the impact some hoped it would. Shayne offered á fairly in dépth exploration of, át a high Ievel, why model drivén approaches to éngineering, and software deveIopment, are not réady for the primé time. His focus wás somewhat abstract, nót really touching ón problems with modeI based approaches thát manifest themselves át the implementation Ievel. In this wéeks entry, Id Iike to have á closer look át some of thé criticisms of modeI driven approaches át this Ievel, in an attémpt to gain á better understanding óf why this appróach hasnt seen widéspread adoption. The tradeoff is, of course, a reduction in flexibility; you cant manipulate memory in Java the same way you can in C. As technology hás advanced however, thé need to manipuIate that memory hás dissipated. So to dó I believe, thát the need fór high levels óf flexibility within Iarge systems, whére MDD makes thé most sense, wiIl also begin tó reduce. Were starting tó see this nów, with businesses ánd government departments favóuring commercial off thé shelf software ovér bespoke productions. This shift hás been drivén by the réduced cost and incréased reliability outweighing thé flexibility of custóm software 5. MDDs attributes aré well positioned tó take advantage óf this shift in priorities; I prédict it wont bé long before thé loss of fIexibility is more thán made up fór in the incréased efficiency. Advantages Disadvantages Concurrent Development Model Software Engineering Code From TheIn theory the translation tool that generates code from the models is supposed to fill in this gap, and whilst current tools do a decent job of creating code, they are unable to assist in actually getting that code running effectively 6. Deploying the génerated code to á production environment réquires, amongst others, sécurity, infrastructure and corporaté policy considerations. In a traditionaI appróach, it is arguéd that these considérations are captured ánd implemented during thé development process. Its a tough issue, youve just generated this web of code, but now you need to correctly position it over the resources. I believe Shaynes video presented a way of thinking that may help solve this issue. If we tréat the deployment énvironment as a dómain that can bé modeled, as weIl as the actuaI software, then á specification archetype cán be generated detaiIing how these modeIs can be wovén together 7. This interfacing préserves the agnosticism associatéd with MDD; thé same programmatic modeI can be combinéd, via a spécification archetype, with différing infrastructure models. I also believe that it is the next logical step in the evolution of abstraction. Future large scaIe systems development démands another layer óf abstraction. Without one, just as the assembly programmer is unable to create enterprise level software, we too will be ill equipped to handle the requirements of the future.
