C4 and Other Approaches

In the previous chapter, we provided an initial idea of the business goal of the sample information system (and application software modules) that we are going to build as a practical exercise to follow the principles outlined in this book. Talking about principles, while introducing the demo system, we also explained how the most important principles in object-oriented programming would apply to the design of our system.

Now that the high-level principles have been set, it is time to go a level deeper in understanding our sample information system, and we will take advantage of this to show a few different methods professionals use. There exist many architectural methods and software representations, as we are going to see, and many overlap in lots of ways. In fact, some of them are so close that they really are a way for their author to mark their individual approach, rather than bringing some additional value to the architectural tools. This is the same...
