SQL stands for Structured Query Language (pronounced SEQUAL or S-Q-L).  Most of the Relational Database Management Systems (RDBMS) support SQL. Therefore, the skills learned for managing data in one database are transferable to managing data on other databases. Also, the programs written in SQL on one database are transferable to other databases with minor changes, especially if the programs are written using ANSI SQL. In 1986, American National Standards Institute (ANSI) initially developed the standards for the SQL language.

PL in PL/SQL stands for Procedural Language.  PL/SQL is a combination of SQL and procedural features of the programming languages developed by Oracle Corporation. Programs written in PL/SQL language are also known as stored procedure because the programs write using PL/SQL language are compiled by the Oracle Database server, and they are stored in the database. During the run-time, the PL/SQL commands are executed within the server for optimal performance. PL/SQL supports both static and dynamic SQL. Advantage of using Oracle’s PL/SQL is that the PL/SQL combines the data-manipulation power of SQL with the processing power of procedural languages.
