Frequent question: Is PL SQL procedural or object oriented?

Is PL SQL object-oriented?

In PL/SQL, object-oriented programming is based on object types. They let you model real-world objects, separate interfaces and implementation details, and store object-oriented data persistently in the database.

Is PL SQL a procedural language?

PL/SQL is Oracle’s procedural language extension to SQL. PL/SQL allows you to mix SQL statements with procedural constructs. PL/SQL provides the capability to define and execute PL/SQL program units such as procedures, functions, and packages.

Is OOP better than procedural?

Security: Object-oriented programming is more secure than procedural programming, because of the level of abstraction or we can say data hiding property. It limits the access of data to the member functions of the same class. While there is no such data hiding in the procedural programming paradigm.

What are the drawbacks of procedural languages?

Disadvantages

  • The program code is harder to write when Procedural Programming is employed.
  • The Procedural code is often not reusable, which may pose the need to recreate the code if is needed to use in another application.
  • Difficult to relate with real-world objects.
