Siebel Enterprise Integration Manager (Siebel EIM) is a server component in the Siebel EAI component group that transfers data between the Siebel database and other corporate data sources. This exchange of information is accomplished through intermediary tables called EIM tables. (In earlier releases, EIM tables were known as interface tables.) The EIM tables act as a staging area between the Siebel application database and other data sources.
In the Siebel application database, there are application tables (known as base tables), which Siebel Business Applications use. For data to come from other corporate data sources (external databases) into Siebel application tables, the data must go through EIM tables. So the data exchanges between the Siebel database and external databases occurs in two phases:
When data is entered through the Siebel user interface, the application references properties set at the business component object type. However, when data is entered into Siebel base tables through Siebel EIM, EIM references properties set at the table object type.
NOTE: You must use Siebel EIM to perform bulk imports, exports, merges, and deletes, because it is not supported to use native SQL to load data directly into Siebel base tables (the tables targeted to receive the data). Additionally, be aware that Siebel EIM translates empty strings into NULL.
