I would like to know what is a good and efficient way to start a data wareshouse for some large tables that we have in one of our production databases? The large tables are about 30 to 40 million records in size. These tables are mostly "reporting" tables that contain historical data that I need to keep in our database. Any suggestions for data warehouse techinques on these tables would greatly appreciated.
If I was to start a data warehouse project from scratch, I'd make sure that I had some training first. Data warehouses are different than normal, online transaction databases. Personally, I took the Data Warehousing Fundamentals class from Oracle Education. It was really good in pointing out the basics.
Aside from that, you'll want to make sure that you use Oracle's best tools available to help with the volume of data you will be handling. Partitioning is a must for such large data volumes. Parallel SQL statements help out greatly too! You'll also want to make sure that you start with Oracle 9i so you can use many of the new analytic features available to you.
