The Datastore is the central database for your Workspace Control environment. It contains all configuration settings of the user workspace. Each computer on which Workspace Control has been installed and that has connection to a Datastore is an Agent of that Datastore.
All computers in a Workspace Control environment connect to this database (optionally through a Relay Server). It runs on a central database server that you have installed prior to installing the Workspace Control Console. The Datastore and its Agents constantly interchange information about changed configuration settings.
See the Compatibility Matrix Workspace Control for a list of supported database types.
