Unified Modeling Language

The Unified Modeling Language (UML) is a general-purpose, developmental, modeling language in the field of software engineering, that is intended to provide a standard way to visualize the design of a system.

UML 2 has many types of diagrams that are divided into two categories. Some types represent structural information, and the rest represent general types of behavior, including a few that represent different aspects of interactions. These diagrams can be categorized hierarchically as shown below

Structural UML diagrams 

• Class diagram
• Component diagram
• Composite structure diagram
• Deployment diagram
• Object diagram
• Package diagram
• Profile diagram

Behavioral UML diagrams 

• Activity diagram
• Communication diagram
• Interaction overview diagram
• Sequence diagram
• State diagram
• Timing diagram
• Use case diagram

Structure diagrams emphasize the things that must be present in the system being modeled. Since structure diagrams represent the structure, they are used extensively in documenting the software architecture of software systems.

Behavior diagrams emphasize what must happen in the system being modeled. Since behavior diagrams illustrate the behavior of a system, they are used extensively to describe the functionality of software systems.

Deployment Diagram

Deployment diagrams are used to visualize the relation between software and hardware. To be more specific, with deployment diagrams we can construct a physical model of how software components (artifacts) are deployed on hardware components, known as nodes.

A typical simplified deployment diagram for a web application would include:

• Nodes (application server and database server)
• Artifacts (application client and database schema

The nodes host the artifacts. The database schema runs on the database server and the application client runs on the application server.

As the name suggests, the deployment diagram shows exactly where each software component is deployed.

Q. The kind of diagrams which are used to show interactions between series of messages are classified as

1. activity diagrams
2. state chart diagrams
3. collaboration diagrams
4. object lifeline diagrams

Answer: collaboration diagrams

A communication diagram in the Unified Modeling Language (UML) 2.0, is a simplified version of the UML 1.x collaboration diagram.A Communication diagram models the interactions between objects or parts in terms of sequenced messages. Communication diagrams represent a combination of information taken from Class, Sequence, and Use Case Diagrams describing both the static structure and dynamic behavior of a system.
