Topic: Data Flow Diagrams (DFD)

DFDs document a process by documenting the flow of data throughout the process. They depict how data interacts with a system. They can be used to engineer a new process, document an existing process, or re-engineer an existing process.

Topic: Unified Modeling Language (UML)

This introduction to the UML covers symbol usage, definitions, and creating diagrams. The UML standardizes what diagrams with what symbols for what situation. The UML is complete with diagrams for analysis, design, and coding. Use use case diagrams to document how users (actors) use a system (a use case). Use class and object diagrams for the design and coding of a system. A class is the prototype for an object. An object has attributes (properties) and the current values of those properties is the current state of the object.
