UML data flow diagrams are used in most software development or system modeling situations, such as IT infrastructure and business systems. Use case, class, and sequence diagrams are the top three UML data flow diagrams that you should become familiar with. Some UML data flow diagrams, as the name implies, attempt to analyze and depict the structure of a system or process. In contrast, others describe the system's behavior, actors, and building components. There are several types of UML diagrams, and each one serves a different purpose, regardless of whether it is designed before or after implementation.
