What is UML ?
A modeling language which provides a standardway to visualize
the design of a systemarchitecture.UML diagrams show the system
activities,components, entities, as well as the way which allthese
parts communicate together.UML has several diagram types and each
one ofthem is used for a different purpose.
3 Main UML Diagram Types
Structural: Emphasize on how the things whichconsist of a system
are structured.Behavioral UML diagrams: Emphasize on howthe system
and it's components are behave.Interaction diagrams: Consist of a
subset ofbehavior diagrams, emphasize the flow of controland data
among the elements of the system.
Structural UML Diagrams
Package DiagramIncludes packages containing use cases orclasses
to illustrate the functionality of a softwaresystem.Uses packages
to represent the different layersof the architecture of a software
system.

Data Model ProfileIt is a UML extension to support the modelling
ofrelational databases in UML.Classes can mapped to database
tables.

Behavioral UML Diagrams
Use Case DiagramA use case diagram is a representation of a
user's interaction with the system and depicting the specif
ications of a use case.

Behavioral UML Diagrams
Activity DiagramActivity diagrams show the overall f low of
control and constructed from a limited number of shapes, connected
with arrows.

Interaction UML Diagrams
Sequence Diagram UML sequence diagrams are used to show how
objects interact in a given situation. An important
characteristic of a sequence diagram is that time passes from top
to bottom.
