The big question is – is SQL & PLSQL still relevant and should you learn it? Well, the answer is: Yes.

SQL & PL/SQL has established itself as the de-facto data access language used across many different industries, that's available in the database. 

This means that SQL & PL/SQL is no longer just used by developers, but folks from many different parallel technical fields that need to store, manipulate,  and access large volumes of data - analyse it with slice and dice concept to derive meaningful business information so as to have the business in competitive edge.

For this reason, SQL and PL/SQL isn’t going anywhere. Its stable in popularity and still dwarfs NoSQL databases on a side by side comparison.

The advantage of PLSQL is

PL/SQL allows sending an entire block of statements to the database at one time. This reduces network traffic and provides high performance for the applications.

PL/SQL gives high productivity to programmers as it can query, transform, and update data in a database.

Applications written in PL/SQL are fully portable.
