Practical UML: A Hands-On Introduction for Developers. The heart of object-oriented problem solving is the construction of a model.
The model abstracts the essential details of the underlying problem from its usually complicated real world. Several modeling tools are wrapped under the heading of the UML™, which stands for Unified Modeling Language™. The purpose of this course is to present important highlights of the UML. At the center of the UML are its nine kinds of modeling diagrams, which we describe here.
Some of the sections of this course contain links to pages with more detailed information. Why is UML important? Let's look at this question from the point of view of the construction trade. Writing software is not unlike constructing a building. The UML is applicable to object-oriented problem solving. Models consist of objects that interact by sending each other messages. Classes are the "blueprints" for objects. Use case diagrams Use case diagrams describe what a system does from the standpoint of an external observer. Class diagrams. UML Interview Questions Part 1. Free source code and programming. Table of Contents Introduction Again i repeat do not think you get an architecture position by reading interview questions.
But yes there should be some kind of reference which will help you quickly revise what are the definition. Just by reading these answers you get to a position where you are aware of the fundamentals. But if you have not really worked you will surely fail with scenario based questions. To give you a practical understanding i have put all the design patterns and UML in a video format and uploaded here.
Download my 500 FAQ Ebook from link below In my previous section we had concentrated on design patterns which is one of the most important fundamentals for architecture interviews. Some of my previous articles i am sure you will love it. Happy job hunting...... (B) Define UML? Unified Modeling Language, a standard language for designing and documenting a system in an object-oriented manner. (I) Can you explain use case diagrams?

There is no doubt about it… in my mind. And when a software design technology loses the programmers it fades away no matter what the academia thinks. This happened because UML was pushed in a direction that most code writers don’t like: it started to look a lot like bureaucratic paper work. If we list what went wrong it starts to look a lot like the mishaps of other committee driven technologies like CORBA for example.
In random order I can list: 1. This one is very big and usually a recipe for failure in the long term. 2. Trying to sell expensive tools for a technology that is not mature enough and only makes promises to the management (just express your ideas in pictures and the code will be generated by our magic wand) can only work in short term. 3. When you try to offer a solution for every problem in a domain, in the end you are not offering anything useful for any problem in that domain.
