Final answer:
A data store in Gane-Sarson Data Flow Diagrams represents a repository where data is stored temporarily or permanently.
Step-by-step explanation:
In Gane-Sarson Data Flow Diagrams, a data store represents a repository where data is stored temporarily or permanently.
It is depicted as a rectangle with a downward-pointing arrow at the top, indicating the flow of data into and out of the data store.
Data stores can represent physical files, databases, or even manual processes that store information.
For example, in a library management system, a data store could be used to represent the library database where information about books and borrowers is stored.
Any process that needs to access or modify this information would have a data flow connecting it to the data store.
