SQL Fundamentals

Structured Query Language concerns both a simple and effective language used for creating, accessing, and manipulating data and database structures. SQL (Structured Query Language) is a computer programming language frequently used to function with relational databases. The term is usually pronounced as the three letters in its abbreviated form.

In the 1980s, IBM developed SQL, or Structured Query Language, as a means of communicating with databases. Even though SQL includes a strict syntax, command order, or word, it is structured to be humanly identifiable. It ensures the purpose of certain basic SQL queries to be found out by non-programmers.

For better readability, the SQL keywords are also presented in uppercase. Some of these can be seen cited here, like, FROM, WHERE and SELECT. Every keyword has a particular inference, so it must demonstrate the database in a certain sequence. SELECT statements seem to be the SQL statements with the most frequent usage.
