Oracal SQL is an imperative 3GL that was designed specifically for the seamless processing of SQL commands.
It provides specific syntax for this purpose and supports exactly the same datatypes as SQL.
Server-side PL/SQL is stored and compiled in Oracle Database and runs within the Oracle executable.

IN memory Databases
An In-Memory Database is a database management system that primarily relies on main memory for computer
data storage. It is contrasted with database management systems that employ a disk storage mechanism.
Main memory databases are faster than disk-optimized databases since the internal optimization
algorithms are simpler and execute fewer CPU instructions.
