The 4 + 1 Model

For this week we have several material to use, and I found it great. First the video that gets us the theory for the 4 different perspective model architecture plus 1, this part of the homework is connected to video that told us a story about the blind men who touched an elephant, and this two are necessary for fully understand the last article, getting combined into this new story about the programmers that found a new program thing and get to understand it in different ways.

Its important to mention first the 4+1 model and each view of it, getting initialy the logical view explaining the behavior of components using state machine or sequence diagrams, the process view that gets the way of communication for the different system processes, also we got the development view that describes the elements and the components for the system in order to be completed, at last for the fourth view we got the physical view giving us the physical distribution for the components as well as the topology of software and could be represented with deployment diagram. At last we got the +1 that represents the use case scenarios view, this one getting importance at the time of the real world interactions getting in situations for the usage of users or other systems.

This 4+1 just gets us to think of the importance of an architect at the software development, we need at least one person to oversee the production, just for getting the expected quality in your product. It's not only about getting the best code, or work with the best database, it's about everything that gets in your way for making software. I feel that I've been just like the blind programmers, that only gets to touch with that little piece of the elephant, but maybe without the guidance of someone else that apparent snake or wall would never had became a hole new and interesting animal as it get.
