In a data warehouse, what is a ‘Control Table’?
Can you give me an example of how a control table is used in a data warehouse?
Sure! Let's say you have a data warehouse with multiple tables that need to be joined together for a report. Without a control table, you'd have to manually map each field in each table to the appropriate field in the report. But with a control table, you can automate this process by simply looking up the metadata for each table.
