general OLTP db and OLAP db question about conversion

edited Dec 23, 2018 4:03AM in Database DataWarehousing (MOSC) 7 commentsAnswered ✓

Hi MOSC,

Typically to create a data warehouse (OLAP db) a shop will set up a dss db specifically set up for OLAP duties.

This data flow could shown in a simplified manner via;  

OLTP-db ---> ETL processes ---> OLAP-db ---> Reports / BI

However, in general, are there any practices/reasoning for converting an existing OLTP db into an OLAP db as far as upgradie paths, migration paths, or other?

Thanks!

Best Regards,

Donald
