DFD juga dapat digunakan untuk pengolahan data erd visualisasi (desain terstruktur). In a Data Flow Diagram, there is a symbol called Data Store, which represents a database table that provides the information needed erd by the system.
In coordination they provide more detail than either diagram would independently. Diagrams that are level 2 or higher illustrate a system’s functioning with increasing detail. The DFD also provides information dfd erd about the outputs and inputs of each entity and the process itself. They are important as they enable effective communication between members of different departments in an organization. ERD (Entitiy Relationship Diagram) merupakan sebuah konsep yang mendeskripsikan hubungan antara penyimpanan (database) dan didasarkan pada persepsi dari sebuah dunia nyata yang terdiri dari sekumpulan objek yaitu disebut sebagai entity dan hubungan.
