In a data flow diagram, which element represents where data is stored?

Explanation:
In data flow diagrams, the symbol that represents stored data is the data store. It signifies a place where data resides for later use, such as databases, files, or repositories within the system. Other elements have different roles: an external entity is a source or destination outside the system boundary, a data flow shows the movement of data between elements, and a process represents a transformation or activity that changes inputs into outputs. Because storage specifically refers to data sitting still for retrieval, the data store is the correct representation.
