Learning one new thing everyday
UML use case diagrams are the primary form of system/software requirements for new software programs under development. The purpose of a use case diagram is to visualize what the system should do (what); at this stage, it does not consider how (how) to do it.

Model-View-Controller (MVC) is a basic design pattern that separates the user interface logic from the business logic. The Model-View-Controller (MVC) pattern is a way of dividing an application into three distinct components; the model, the view and the controller. This model-view-controller can be best described visually using robustness analysis in stereotyped UML notation, which was first proposed by Ivar Jacobson in his award-winning book Object-Oriented Software Engineering.

Instead of writing hundreds of pages of documentation, it would be convenient to draw a few diagrams to show how it all works. UML diagrams keep the conversation focused, facilitate communication, allow less time to be wasted on explanations, and give more clarity to the problem. Thus, UML gives a standard approach to writing a system model that covers conceptual ideas. Through the understanding of modeling, the use and application of UML can make the software development process more effective.

Class diagrams are useful in many phases of system design. During the analysis phase, class diagrams can help you understand the requirements of the problem domain and identify its components. In object-oriented software projects, the class diagram created in the early stages of the project contains classes that are often converted into actual software classes and objects when writing code.

The Unified Modeling Language (UML) was developed to create a common visual modeling language for the architecture, design, and implementation of the structure and behavior of large software systems.UML has applications outside of software development, such as industrial processes. This is an introduction to UML. You will learn what UML is, what the history of UML is, and a comprehensive description of all UML diagram types.

A simple state is one which has no substructure. A state which has substates (nested states) is called a composite state. Substates may be nested to any level. A nested state machine may have at most one initial state and one final state. Substates are used to simplify complex flat state machines by showing that some states are only possible within a particular context (the enclosing state).

A state-transition diagram presents a sequence of states that an object goes through during its lifecycle. It is used to describe the changes of states for an object or for a component.

The behavioral things is the dynamic part of the UML model. These are the verbs of a model. Represents actions in time and space. In general, there are two main kinds of behavioral things. (1) Interactions (2) state machines. They are the basic behavioral things that you may include in a UML model, typically the state machine diagram. Semantically, these elements are usually connected to various structural elements, primarily classes, collaborations, and objects.
