Remember when there were times when you used to jot down important stuff that
you chances were that you probably remembered to do that important but there are
much better odds that you forgot about that task and have just gotten about with
Certainly if you compare now big businesses used to store their important
information you can just tell that there was a problem here that needed addressing.
SQL was invented by IBM researchers in the 1970s. SQL is a programming language
that is used to interface with databases. It understands and analyzes database tables
that include data fields. For example, take a large organization that has to store a lot
of data. The organization collects and stores information from various departments.
All the gathered information is organized and stored in a database, but it has to be
valuable and accessible that's where SQL comes in.
You may ask by looking at the above paragraph that what is a database concept? A
database is basically a brick of data which stores information in the form of tables.
SQL is a powerful language that can help manage and modify large volumes of data.
Some important SQL commands include: SELECT, DELETE, CREATE DATABASE,
INSERT INTO, ALTER DATABASE, CREATE TABLE, and CREATE INDEX. SQL is the most
popular language for accessing databases as it is compatible with all databases.
Advantages of learning SQL
1) Universal Language: One of the methods that crosses over into many different
areas is SQL. Working with SQL involves speaking computer language. This
motivates you to advance into programming using other languages, such as
demand.All you need to succeed with a programming language is a vision of
the industry you want to work in. You can improve your skills to specialise as a
programmer, developer, manager, and more during the time you spend
learning SQL. Although it seems corny, there are virtually no restrictions on
what you can accomplish with SQL.
2) Easy to Learn: SQL is an open-source programming language, so it has a large
developer community. Many SQL and MySQL-related topics are consistently
posted on StackOverflow. SQL is easier to learn than other programming
languages such as C++. Furthermore, many popular SQL databases (MySQL,
MariaDB, and Postgres) are open-source.
3) Able to manage millions of data: Traditional spreadsheets can only handle
small-to-medium-sized data sets, so we'll need an alternative solution to
handle such massive data sets. Fortunately, this is a field where SQL shines:
whether it's 1,000 records or 100 million, SQL is completely capable of handling
