Siebel Enterprise Integration Manager (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 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 parts:
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 EIM, EIM references properties set at the table object type.
NOTE: You must use EIM to perform bulk imports, exports, merges, and deletes, because Siebel Systems does not support using native SQL to load data directly into Siebel base tables (the tables targeted to receive the data). You should also be aware that EIM translates empty strings into NULL.
