The Generate Extraction Script feature allows you to generate script files that will be used to fill and update tables in a data warehouse or data mart database.
The link between the operational database and the data warehouse or data mart database is a relational to relational mapping.
For more information about relational to relational mapping, see "Relational to relational mapping" in Chapter 12, Object Mappings in the Core Features Guide .
You can generate a script file for each data source, you can also select the tables in the data source which select orders will be generated in the script file. The extraction scripts list all the select orders defined in the table mappings.
