Before moving towards the difference between SQL and MySQL, it is more important for us to have a brief introduction to SQL and MySQL. SQL is actually a language that is used for making different queries for the data in a relational type of database and it is the standard querying language for such databases. On the other hand, MySQL is a relational type of database management system and it is also one of the most widely used databases in the world.
Also, I’ll explain everything that is necessary for you to understand the difference between SQL and MySQL. I want you to follow along till the end of this article carefully in order to get to know about it in detail.
1. Understanding the difference between SQL and MySQL
1.1 What is a database?
In simple words, the database is an organized system for storing data in a structured and systematic form electronically either online or offline it is controlled by a DBMS and it mostly uses SQL for writing and querying data.
1.2 What is a DBMS?
A DBMS is also known as Database Management System which is software for storing the data in a database and retrieving it. A DBMS allows users to create as many databases as they wish to according to their requirements. Inside a DBMS there are certain programs that handle or control the database in various ways and make it easy for the user to access it.
1.3 What is SQL?
SQL is also known as Structured Query Language, which is used in a DBMS for storing and querying or managing data. It is used in the relational type of database management systems and it is also a standard language for such types of databases. The best example of RDBMS which is most widely used today is MySql.
So, SQL databases are those that use SQL as a querying language for storing and managing the data.
1.4 What is MySQL?
MySQL is an open-source relational database management system for storing data. It is written in C and C++ programming languages and its base were developed by a Swedish company in 1995. One of the most premium features of MySQL is that it is cross-platform and it works for almost any type of platform e.g. Windows, Linux, Mac OS, etc.
It uses SQL(Structured Query Language), which is a standard language for relational types of databases. MySQL is a fast and easy-to-use RDBMS and it is used by all kinds of businesses either small scale or large scale for storing data because we can store data in it persistently.
1.5 Why it is not a good choice for us to explain the difference between SQL and MySQL?
It is an obvious thing that SQL(Structured Querying Language) and MySQL databases are totally different things but because of their functionality, they are both deeply connected to each other. It won’t be wrong to say that MySQL being a purely relational database management system is dependent on SQL in one way or the other.
Both being totally different things it won’t be a good choice for us to explain the difference between SQL and MySQL, rather than differentiating both, it would be better to explore the features of SQL & MySQL in detail.

2. Functioning of SQL
Now in order to understand the functioning of SQL we have to cover a few important concepts first which are really easy to understand and are important to be understood because they play the most important role in the working of SQL(Structured Query Language):
3.1 DDL (Data Definition Language)
DDL is also known as Data Definition Language and it provides a set of definitions for specifying the structure of the databases e.g. tables, etc., and also the access methods for that database. The commands used by DDL are Create, Drop, Rename, and Alter.
3.2 DML (Data Manipulation Language)
DML is also known as Data Manipulation Language and it provides and it allows the user to access data as it is organized by the appropriate data model e.g. the relational model. The commands used by DML are Insert, Update, and Delete.
3.3 How are DDL and DML connected to SQL(Structured Querying Language)?
SQL uses DDL and DML commands in its work and SQL also uses these commands for defining the relation between structures of a whole skeleton structure of the entire database, deleting relations, and modifying the relations.
3. What are the main features of the MySQL database?
Relational databases have the following main features that are enlisted below:
- Relational databases have a tabular model that constitutes rows and columns and they are in a very organized form which makes them properly structured and secure.
- They are usually used for relatively faster data storage and easy retrieval of data from the databases which makes it easy for us to perform various functions with our data.
- SQL(Structured Query Language) is usually used to insert, search, update, and remove data and it is also the standard querying language for relational database management systems.
- In relational databases data is stored in the form of columns and rows, where each column represents some attributes and each row represents some record of data.
- The most important feature of a relational database is that it has a unique key for each table and it refers to each table with that unique key. One can also use these unique key fields to connect the data of one table with another table.
4. What are some main points that differentiate MySQL from other databases?
- Oracle owns MySQL and it is an open-source database management system.
- MySQL is much more popular and is one of the world’s most widely used database management systems.
- MySQL is faster and more efficient in terms of memory performance and intensive reading operations.
- It has a drawback that it has some functional limitations i.e. it lacks support for FULL JOIN.
- MySQL is a purely relational database management system.
- It adheres to SQL standards but not as closely as PostgreSQL does.
- MySQL is better at handling concurrency but it is not best for it.
- MySQL is not that extensible and lacks support for advanced data types.
- It is a conventional relational database and it is not as friendly toward the integration of new data sources and extensions.
- In terms of security, MySQL is somewhat equally good as PostgreSQL.
This article takes the readers from the very basic concepts like what are databases to the comprehensive definitions of SQL and MySQL databases along with the functioning of SQL and features of MySQL database.
The purpose of discussing all the related concepts is to provide you with a proper understanding of SQL and MySQL databases.
