- An actual data flow diagram differs from a conceptual data flow diagram in that the latter is more particular while the former is more generic.DFDs are becoming more popular as a data and processing paradigm, and this popularity is expected to continue to grow. Have you given any attention to the many factors that may have led to this circumstance?Explain the use of Unified Modeling Language (UML) diagrams in data modeling and provide examples of different UML diagrams used in data modeling.
