FlowChart

* is a diagram that describes a process or operation. It includes multiple steps, which the process "flows" through from start to finish. Common uses for flowcharts include developing business plans, defining troubleshooting steps, and designing mathematical algorithms.

Data Flow Diagram

* is a graphical representation of the flow of data through an information system. It enables you to represent the processes in your information system from the viewpoint of data.

Entity Relationship Diagram

* is a graphical representation of the flow of data through an information system. It enables you to represent the processes in your information system from the viewpoint of data.

Structure Chart

* is a graphic depiction of the decomposition of a problem. It is a tool to aid in software design. It is particularly helpful on large problems. A structure chart illustrates the partitioning of a problem into subproblems and shows the hierarchical relationships among the parts. A classic "organization chart" for a company is an example of a structure chart.

Case Diagram

* is a representation of a user's interaction with the system and depicting the specifications of a use case. A use case diagram can portray the different types of users of a system and the various ways that they interact with the system.

Class Diagram

* provides an overview of the target system by describing the objects and classes inside the system and the relationships between them. It provides a wide variety of usages; from modeling the domain-specific data structure to detailed design of the target system. With the share model facilities, you can reuse your class model in the interaction diagram for modeling the detailed design of the dynamic behavior.

Sequence Diagram

* is an interaction diagram that shows how processes operate with one another and in what order. It is a construct of a Message Sequence Chart. A sequence diagram shows object interactions arranged in time...
