Class & Sequence Diagram

Unified Modeling Language is….

• A system development technique that uses a graphical language to document, visualize and perform system specifications

• A diagram that describes the interaction between objects in and around the system in the form of messages depicted against time

• A diagram used to describe the pattern of classes and relationships between classes of a system

• Some graphic diagrams, some of which are use case diagram, activity diagram, class diagram, sequence diagram, component diagram, deployment diagram and others

benefits of class diagram, except…

• Illustrate data models for information systems, no matter how simple or complex

• Easier to understand the general overview of the schematics of an application

• Create detailed charts that highlight any specific code needed to be programmed and implemented to the described structure

• Provides a modeling language that is independent of various programming languages and engineering processes

The relationship between classes has a description called multiplicity
