"Mach-II Architecture: Under the Hood" interview with Ben Edwards ******************************************************************** Michael Smith: Im speaking with Hal Helms. Hal is going to be talking at CF_Underground on domain models andwell, Hal, why dont you explain what youll be talking about? Hal Helms: Youre exactly right: Im talking about domain models and how their proper use can help application developers build a true application environment. MS: Two things jump out: proper use and application environment. Explain those. HH: OK, first, lets start with what a domain model is. Lets take the conferences you produce as our domain. What kind of things make up these conferences? MS: Well, we have speakers, of course, and then topics. And theres a venue. And a coordinator. There are staff involved. There are sponsors. HH: Thats good enough for a start. Now, those things you mentionedspeakers, topics, venues, etc.those are the stuff that makes up the cfconference domain. Those are the things that make up that world. MS: Right. HH: And these things have relationships with one another. For example a speaker has a particular topic that s/hell be giving at a particular conference in a particular venue. All of those are related. MS: Yes HH: Well, the proper use I spoke of means that we do two things. First, we get the relationships rightand by right, I dont just mean accurate: I mean we relate them in ways that can withstand the shocks our domain model will sustain when change happens. MS: Change HH: Yes, its absolutely going to happen and its the hardest thing to plan for since, by its very nature, we cant predict it. But our domain modelboth the entities and the relationshipsneed to be able to continually adapt to the evolution of our applicationand even the evolution of the domain itself. MS: How do you design a domain model to be able to adapt to things we cant predict? HH: Two important things: and API and the judicious use of design patterns. MS: An Application Programming Interface? HH: Yes, this means that we think of the app as a collection of services that we can call on rather than thinking in terms of specific algorithms and particular ways of storing data. MS: But ultimately well have to get to those. HH: Sure, but by designing to a specification (the API) and not the implementation, we give our app the ability to change without breaking. MS: So if a particular algorithm were to change, the API would still remain the same? HH: Good example for you: when CF went from 5 to 6, the underlying implementation changed greatly. MS: Yes, it went from C++ to Java! HH: But the underlying APIthose tags and functionsremained the same, at least in great measure. That meant that our applications built on this API didnt break even though the underlying implementation went through a radical change. MS: And design patterns? HH: You could look at design patterns as having a really experienced consultant helping us avoid mistakes in setting up our domain model. MS: OK. You also said application environment. HH: Yes. You notice than in talking about your domain model, we didnt say anything about any specific application. MS: Hmmm true. HH: Thats because your domain model should be somewhat application-agnostic. In other words, the notion of a Speakerwhat a Speaker knows about itself and the sort of things a Speaker can doshouldnt change from application to application. MS: True: a Speaker is a Speaker. HH: So as we build our domain model, were building an environment in which it becomes progressively easier to build apps. The application defers more and more work to the domain model. This brings up one big advantage that employees have over consultants. Because employees are typically at a company for several years, the work they put into the domain model has a chance to really pay off. For consultants, employed for a few weeks or months, there just may not be enough time/money for this. MS: It sounds like youve got a lot to say on this subject. Ill look forward to hearing more at CF_Underground.
