Oracle PL/SQL Important Topics

Oracle is a relational database technology.

PLSQL stands for "Procedural Language extensions to SQL", and can be used in Oracle databases. PLSQL is closely integrated into the SQL language, yet it adds programming constructs that are not native to SQL.

We've categorized Oracle and PLSQL into the following topics:
