About Siebel Enterprise Integration Manager
Siebel Enterprise Integration Manager (EIM) manages the bidirectional exchange of data between the Siebel Database and other corporate databases. This exchange is accomplished through intermediary tables called EIM tables. (In earlier releases, these tables were known as interface tables.) The EIM tables act as a staging area between the Siebel Database and other databases.
You must use Siebel EIM to perform bulk imports, exports, updates, and deletes. Using native SQL to load data directly into Siebel base tables (the tables targeted to receive the data) is not supported.
For more information about Siebel EIM, see Siebel Enterprise Integration Manager Administration Guide. See also Siebel Performance Tuning Guide.
