MySQL is an open-source database management system (DBMS), which means it is freely available for anyone to use, modify, and distribute. This makes it a popular choice among developers and businesses looking for a cost-effective solution for managing their data.

One of the main advantages of using an open-source DBMS like MySQL is the active community of developers who contribute to its development. This ensures regular updates, bug fixes, and new features are constantly being added to improve its performance and security.

Stores data in tables with rows and columns

In MySQL, data is organized into tables consisting of rows and columns. Each row represents a record or entry in the table, while each column represents a specific attribute or field associated with that record. This tabular structure allows for efficient storage and retrieval of data.

For example, let’s say you have a table called “Customers” that stores information about your customers such as their names, addresses, phone numbers, and email addresses. Each customer would be represented by a row in the table, with each attribute stored in its respective column.

Uses Structured Query Language (SQL) for managing databases

MySQL uses Structured Query Language (SQL) as its primary language for managing databases. SQL provides a standardized way to interact with the database by allowing you to create, retrieve, update, and delete records from tables.

With SQL commands such as SELECT, INSERT, UPDATE, and DELETE, you can perform various operations on your MySQL database. These commands allow you to extract specific information from tables based on certain conditions or criteria.

For example:

  • SELECT * FROM Customers WHERE City = ‘New York’ retrieves all customers from the “Customers” table who are located in New York.

MySQL also supports advanced SQL features such as joins, views, and stored procedures, which provide additional functionality and flexibility when working with your data.

Basic functionality of MySQL databases

MySQL is a powerful and widely used database management system that offers a range of functionalities for creating, modifying, and deleting databases. Let’s dive into the basic functionality of MySQL databases to understand how they work.
