Explanation:
* Multiprocess and Multithreaded Oracle Database Systems
Multiprocess Oracle Database (also called multiuser Oracle Database) uses several processes to run different
parts of the Oracle Database code and additional Oracle processes for the users—either one process for each
connected user or one or more processes shared by multiple users. Most databases are multiuser because a
primary advantage of a database is managing data needed by multiple users simultaneously.
Each process in a database instance performs a specific job. By dividing the work of the database and
applications into several processes, multiple users and applications can connect to an instance simultaneously
while the system gives good performance.
* In previous releases, Oracle processes did not run as threads on UNIX and Linux systems. Starting in Oracle
Database 12c, the multithreaded Oracle Database model enables Oracle processes to execute as operating
system threads in separate address spaces.
