Since last couple of days, I am receiving lots of questions about Standard Query Language (SQL). I also saw that there was a lot of confusion about Oracle SQL. So, I have decided to answer all your doubts once and for all. Let’s do that.

What is SQL?

SQL stands for Standard Query Language. It’s a non-procedural programming language. SQL is in-fact a fundamental programming language for communicating with a relational database.

This non-procedural programming language was designed by IBM in 1970. The main aim of IBM for designing SQL was to work with its database system called ‘System R’. Since the syntaxes of SQL language resembles a lot with English thus in its earlier days it was called SEQUEL (Structured English Query Language).

If you are developing an application which requires you to save some application or user data, for example username, password or anything you need a database. And, to communicate with that database, you need a programming language and that is SQL.

But still here are the books which I used in order to learn Oracle SQL and pass this exam –

  1. SQL, PL/SQL by Ivan Bayross.

I started learning SQL through this book back in my college. It’s a good read for basic SQL and PL/SQL knowledge. I love that in this book Ivan has used small projects for explaining the concepts, those were of huge help.

The database version used in this book for explaining the concepts is Oracle Database 9i. We have come a long way from this version, and it has become obsolete now. This is the only drawback of this book. Click here to buy this book
