Sample OOD/OOAD code and application illustrating a real business application
in [OOP]
|
From: jaffarkazi on 3 Dec 2007 09:01 Hi. I've read a lot of tutorials on OOAD and do actual design and coding also. What I would like to have is a real world sample application that totally illustrates OOAD as how it would be done when implementing a production system, as a learning tool. This sample would obviously be without any UI and database, etc. Just the basic objects that would be used in a normal business application illustrating total OO usage for a real app. eg. Inventory, etc. Regards, --Jaffar

From: jaffarkazi on 5 Dec 2007 00:48 Hi, Thanks for this, but I'm having difficulty getting this book. Is it possible for you to suggest something else? Also, even if it's not a book but just some simple code, that would also be very helpful. Regards, --Jaffar H. S.

The tricky part is finding a complete application as an example. Most authors use examples that are subsets of larger problems to illustrate specific points. So I don't know of any offhand. However, I can suggest two other books that should be available. "Executable UML: How to Build Class Models" by Leon Starr. This is, far and away, the most comprehensive book on class modeling available. There are lots of disparate examples but Leon does a pretty good job of discussing trade-offs and the underlying logic of Why one wants to do things a particular way. "Executable UML" by Balcer and Mellor. Again, disparate examples. However, Mellor is the best modeler I know and the examples in the book provide a lot of design insight into things like abstracting invariants (e.g., his model of a subsystem for managing a browser UI is a classic example of abstraction so that the subsystem can be reused across applications with different UIs.) [BTW, the "executable UML" is not a personal bias. Starr and Mellor are translationists and code generators are notoriously literal minded; they do what you say, not what you meant. They also both grew up in R-T/E, which is a very unforgiving environment for software design. So they both needed a very rigorous approach to design modeling. So the "executable UML" comes from the fact that both provide models that are complete, precise, and unambiguous -- which enables execution of the models themselves for validation purposes. IMO, that rigor should be applied to any OO design if one wants to avoid downstream problems, even if one manually codes. If one has thought through the design to the point where an R-T/E code generator can deal with it correctly, that should be good enough for a human programmer.] ************* There is nothing wrong with me that could not be cured by a capful of Drano.

OO fans like to wrap them away and pretend like they don't exist in order to obtain OO purity, but if they do such, they often end up reinventing the database wheel.
