Weekend Learning: Oracle Database - Information Centers

Do you enjoy finding new Information Center documents on My Oracle Support?  If so, tonight is your night!  I introduce not just a single Information Center, but a bevy of them if you follow article "Index of Oracle Database Information Centers" via document ID 1568043.2!  This document has many different facets about Oracle's flagship database product in addition to many different things like Engineered Systems such as Exadata, Exalytics, Exalogic, Big Data, and SPARC plus Embedded Database systems like TimesTen or NoSQL!  Looking for GoldenGate, Audit Vault, or MySQL?  You are in luck!  Documents for these are found here too!

What is Exalogic?

This post took me over to a great document where page 17 gave me a great visual showing just what the difference between Exadata and Exalogic is.  If you ever wanted to know, I strongly suggest you go look at this PDF to find the answer!
