What is Oracle?
Oracle is such a complex system that without analogies it's
really very hard to comprehend and grasp the concept of Oracle
architecture and its working. If you are new to Oracle or an
experienced DBA, understanding of concepts is the key to
success not only in Oracle Certifications but in real world. Also
once you understand the concepts then there is nothing left for
cramming.
Oracle System is basically divided into two things namely
Oracle Instance and Oracle Database. We have taken the analogy
of a Genie (Ghost/Djin): just like the one you might have seen in
the movie/story of “Aladdin & the Magic Lamp”. When Aladdin
rubbed the lamp; Genie became available and fulfilled all his
commands. Similarly when you double click “Oracle” icon in
your system, Oracle Instance gets alive and waits for users
information/data related commands to fulfill, as it is a
magnificent “Data Management Genie”.
