Question

Quizplus · Accepted Answer

A data store is a container for holding data in a structured way. It is represented by a rectangle with a noun-phrase label that describes the type of data it stores. Therefore, option C is the correct statement. Option A is incorrect because data cannot move directly between data stores; it must be processed and transformed by a process before moving to another data store. Option B is incorrect because relationships between entities are illustrated by data flow diagrams. Option D is incorrect because a data store can only hold data that already exists, and it cannot create or generate data. Option E is incorrect because a data store is a static representation of data, and it does not show data in motion.
