%META:TOPICPARENT{name="GlossaryEntriesD"}% ==Glossary of Technical Terms== ==Database Agent == A database Agent is the only database-specific component in OpenLink's Multi-Tier architecture. In fact, these agents are built against a database's CLI. When the OpenLink Request Broker receives a connection request, it spawns the appropriate agent. Then, the agent retrieves data from the database and returns it to the calling client.
