Managing Data
Data stores are used in architecture diagrams to represent data that must be stored to be share between components.

A data store provides a mechanism to update or consult data that will persist beyond the scope of the current process. It enables storage of input message flows, and their retransmission via one or several output message flows.
A data store references an data domain.

A data area represents a restricted data structure dedicated to the description of a software Data Store. It is made of classes and/or data views and can be described in a Data Area Diagram.
