This chapter covers the basics of Oracle architecture. We start with some clear definitions of two terms that are very misunderstood by many in the Oracle world, namely instance and database. We also explain the architecture of container and pluggable databases. We take take a quick look at the System Global Area (SGA) and the processes behind the Oracle instance, and examine how the simple act of “connecting to Oracle” takes place.
