Data Object Layer...

• a logical representation of the underlying physical database, which includes tables, columns, indexes
• provides a way to administer and restructure relational databases in Siebel CRM
• Siebel CRM generates queries in response to a user action, processes the query results that it returns from the RDBMS up through the relevant object definitions in the architecture, and then presents the results to the user

For example, if we want to create/alter/delete a column in a table, we can perform the respective change in Siebel Tools which is having the schema definition (metadata), then by applying the changes will get reflect in table level in the database.

we will see more details about "performing Table/Column/Index configuration change" in path Siebel CSW >> Configuration >> Configuring Table Object

Objects in Data Object Layer...

Columns

• is a representation of the physical column in the underlying database management system
• in this layer, we can create / alter / delete one or more columns from a table schema

Table

• is a logical representation in the Siebel repository of the physical table that resides in the underlying RDBMS
• in this object layer, we can create a stand-alone table / extension table / 1:M relationship table / an inter table (for M:M relationship)
