Why is the snowflake schema normalized, even though the data warehouse has the property of being denormalized? I am learning about data warehouse technologies, can anyone elaborate on this for me?
I apologize if I am missing something here, I am open to suggestions. :)
Thanks!

I am a final year IT student and I need a dataset to create a data warehouse. I tried searching on Kaggle and on open data but could not find the right one. Is there any source for a large free data set I can use for Business Intelligence purposes? Any help would be greatly appreciated!
Microsoft have a few - AdventureWorks is the one I've used in the past.

I'm looking for guidance or instructions to allow Information Server's DSODB database to be located on a Netezza Appliance.
has anyone been able to do this?
I realize the guidance say ORACLE, MSSQL, and DB2, but if anyone knows how to put it on Netezza, that would be of great interest.
Thank you.
I suspect it is more than just guidance to use Db2, Oracle or SQL Server. Likely only those DBMS are supported for the operations database. Netezza is lacking things like indexes and enforced primary and foreign keys, so is likely not suitable for the DSODB
I'm deciding what database to use for my project, but I've only ever used relational databases (Oracle, MySQL) so for my web project I figured I'd use MySQL with PHPMyAdmin for DBMS.
But I'd like to know more about other database types, succinctly if possible, before I finally decide.
Thanks in advance!
I was wondering if there was any other alternative in order to skip the classical three or more steps normalization in Databases Topic.
Somebody told me that if I used the relational graph technique I could get all my database as a normalized database without having to do all the three or more steps of normalization.
Any idea?
Thanks in advance!
