Home -> Community -> Mailing Lists -> Oracle-L -> RE: 8i or 9i for Data Warehouse
Oracle 9i has more data warehouse functionality. ETL with external tables is beneficial depending on your data transformation requirements.
If your using the star schema. Bit mapped indexes on the fact tables for each dimension could really increase your performance with either version 8i or 9i.

Hi everyone -
I have been asked to do the database planning for a fairly large data warehouse. The warehouse is currently in Sybase and is about 160 GB. They are planning to move to Oracle very soon.
My questions - does it make more sense to spin it up on 8.1.7 or 9? (This will be a pretty good size Solaris machine). Are there newer features in 9i that would really benefit them? I am looking at partitioning tables and using some bit-mapped indexes - something they don't have today. I was originally looking at 8.1.7, but now that 9 has been around for a little bit, I'm wondering if any of you have some advice (good or bad) regarding version 9.
Any and all comments are appreciated.
Thanks -
lisa
