SQL is the most popular fourth generation programming language. A fourth-generation language is framed keeping in mind the convenience of users in comparison to machine languages, assembly languages, and the earlier high-level languages. SQL programming can be used optimally for searching and modifying database records. Being a procedural extension of SQL, PL/SQL (procedural language extensions to the structured query language) allows writing procedural codes that comprise SQL.
PL/SQL program units are efficiently compiled by the Oracle database server and stored within the database. During run-time, both PL/SQL and SQL run within the scope of the same server process, thereby generating good efficiency. The best part is that PL/SQL automatically inherits the security, dynamic nature, and portability of the Oracle database. If you want to learn about how to create and manage PL/SQL program units, PL/SQL datatypes, the role of SQL in PL/SQL, etc. enroll in the Best PL/SQL Training Institute in Chennai.
