I have a large software system with millions of SLOC, hundreds of modules, and thousands of interface dependencies. Based upon an earlier question in StackOverflow I have been able to start discovering what these interface dependencies actually are. The challenge now is to have all this information available in a useful format. The da...
Hi, I'm thinking of buying Martin Fowler's "Patterns of Enterprise Application Architecture". From what I can see it seems like a great book, it an architectural book with bias towards enterprise Java -- just what I need. However, in computer years, it is quite old. 2003 was a long time ago, and things have moved on quite a bit since t...

Model Driven Architecture is the idea that you create models which express the problem you need to solve in a way that is free of any (or at least most) implementation technologies, and then you generate implementation for one or more specific platforms. The claim is that working at a higher level of abstraction is far more powerful and ...
When designing libraries, I often end up resorting to the following pattern, which I don't like as it results in lots of type-casting. The basic pattern is: The code using the library hands an object to the library, the library then hands the object back to the calling code. The calling code is forced to cast the object, as the library ...

I don't really see the point of UUID. I know the probability of a collision is effectively nil, but effectively nil is not even close to impossible. Can somebody give an example where you have no choice but to use UUID? From all the uses I've seen, I can see an alternative design without UUID. Sure the design might be slightly more c...

Could someone explain the difference between software design and software architecture? More specifically; if you tell someone to present you the 'design' - what would you expect them to present?
