Oracle is the #1 database and has the most advanced feature set. Oracle is made up of a set of processes running in your operating system. These processes manage how data is stored and how it is accessed. I will cover these processes in detail in the future; but for now we just need to understand that Oracle is a program that is running in the background, maintaining your data for you and figuring out where it should go on your hard drive.
Oracle’s strategy is to offer a broad portfolio of software and hardware products and services to enable public, private and hybrid clouds, enabling customers to choose the right approach for them. Unlike competitors with narrow views of the cloud, Oracle provides the broadest, most complete, and integrated cloud offerings in the industry.
