About the Siebel Database Server
The Siebel Database Server stores the data used by Siebel eBusiness Applications. Siebel Dedicated Web Clients, Siebel Tools Clients, and Siebel Server components connect directly to the Siebel Database Server and make changes in real time. Dedicated Web Clients download a subset of the data to use locally, periodically synchronizing with the Database Server through the Siebel Server to update both.
Installation of the Siebel Database Server software provides files with which to install Siebel Database and Siebel Database Server components and to import the Siebel Repository.
The Siebel Web Client connects to the Siebel Server, which accesses the Siebel Database.
