Why warehouse, database won't suffice for providing data for analysis?
Javier Campos (4 years ago)
Different reasons, the first is that a transactional database (used by your system) is optimized for transactions and sessions not for analyitical queries, these may eventually slow down the database's response time to a functioning system so problems on speed are shown to the users. On another hand, a data warehouse's structured is optimized for analytical queries, it's not a copy of a transactional database but a condensed one based on the considered important data.  Another reason to recomend is when a company has different systems working on different databases, you may want to unify the data on a single structure on which you want to get reports.

Clear, simple, voice is nice, timing is good, I was appreciative of the text along with the voice and pictures, informative for beginners (and that's why it's an introduction :). Thank you. I'd likely choose one of your videos if it was on a topic I was interested in.
