What Is SQL?

SQL is a query language used to get data from databases. Although it cannot be used to build applications, it can communicate with the relational database systems built into many apps. All software interacts with data in one way or another, so the increasing demand for apps of all sorts means that SQL is very popular right now.

4 Reasons to Start Your Tech Career with SQL

Here are four excellent reasons why you should start learning SQL before any other technology:

  1. SQL IS A COMMON STANDARD

During the last four decades, SQL has become a universal database query language. It was created by IBM engineers in the early 1980s, which means it has a long history. It has achieved widespread use and acceptance, and it is very well documented.SQL was the first DBMS (Database Management System) language deemed as a standard in relational database communication by American National Standards Institute (ANSI) and the International Organization for Standardization (ISO).

SQL is used by all database management systems, from the lightweight (SQLite) and open-source (MySQL, PostgreSQL) to the commercial and closed-source (Oracle, SQL Server, IBM DB2). Each vendor’s implementation of SQL is slightly different, but the core language is the same. You can learn the basics of the language before you decide which database to use.

Over the years, SQL has kept its industry-leading position. There is no reason to believe this will change in the near future.

  1. SQL IS EASY TO LEARN

SQL is easy to learn, even for IT beginners. Most common programming languages – such as C# or Java – are imperative languages. This means that you need to specify a step-by-step procedure to solve a problem, using a series of statements. SQL is a declarative language: the user tells the system what data to deliver and the SQL engine does the rest. The query either works or fails. You only need to know what data you want; it’s not your job to determine how to get it.SQL is also a high-level programming language, one that was designed for non-technical users. It resembles a natural language, so it’s easier for humans to read.  It hides the entire data transition process from the user, so you don’t have to concern yourself with specifying how you want the results to happen.

 

  1. SQL IS WIDELY USED

SQL databases tend to fit a lot of solutions quite well; they are tested, stable and scalable. It is a common standard for all relational databases. All major DBMS platforms support SQL. If you know SQL you can easily switch from one database to another.

  1. SQL IS VERSATILE

Almost every organization needs SQL-fluent pros. This knowledge is essential for database professionals, like developers and administrators. Even if you’re not aiming to become an admin or a developer, SQL skills will certainly be worthwhile. Data analysts, data scientists, Big Data engineers, and even marketing specialists can use SQL. For example, with a bit of SQL knowledge, marketers can extract specific information from huge amounts of data.
