Research Paper Easy-Compare Entity-Relationship (ER) diagrams, Structured Analysis and Design Technique (SADT) diagrams, data flow diagrams (DFD), and Unified Modeling Language (UML) use cases

Imagine that you have been working on a project to design and build a given system. You have completed the elicitation and evaluation phases and now you need to specify and document the system-to-be. Suppose you have decided to use diagrammatic notations for the specification and documentation. Your options are to use context diagrams or frame diagrams. Evaluate each type of diagram and select the one you feel is the best fit. Provide a rationale.

Compare Entity-Relationship (ER) diagrams, Structured Analysis and Design Technique (SADT) diagrams, data flow diagrams (DFD), and Unified Modeling Language (UML) use cases. Determine which diagram you are most likely to use for your system documentation. Provide a rationale.
