What Is MySQL Database?

• MySQL Database Definition

  MySQL Database Definition

  MySQL is an open-source, ACID-compliant enterprise relational database solution. It supports most operating system platforms, including Windows, macOS, and Linux. It operates on a client-server model where client computers leverage the Structured Query Language (SQL) to send data requests to the MySQL database server. MySQL is also used in many web-driven database applications and is an integral component of the LAMP software stack, which consists of Linux, Apache, MySQL, and Perl/PHP/Python.

  MySQL is configurable, secure, scalable, and simple to use. As a secure relational database management system (RDBMS), it enables fine-grained authorization access control and data encryption to protect user data. It offers robust performance and on-demand scalability options for distributed computing environments. The industry-wide acceptance and usability of the MySQL database server make it a good choice for rapid, cost-effective application development.

  Paid support is available through Oracle via its MySQL Enterprise products, and from third-party vendors, support, and service organizations.

  What is MySQL database used for?

  The MySQL database management system has multiple use cases in companies, from data analytics, warehousing, security, and backup to data migration. However, the most common application of MySQL is to create a database backend for web applications. Most database-driven web apps rely on the open-source LAMP  stack, in which MySQL stores and manages application data. Companies generally use the MySQL database server with one of two storage engines: InnoDB (the default) and MyISAM (a legacy option). The former is chosen for ACID-compliant transaction-oriented applications, such as online banking, while the latter is preferred for non-transaction-oriented environments or data warehousing.

  Many enterprises prefer the advanced features available in Oracle MySQL Enterprise Edition, which offers robust security features, such as transparent data encryption (TDE) and user authentication. For mission-critical applications with high availability requirements, companies generally use the Oracle MySQL Cluster CGE edition, as it includes features such as server replication and automatic failover. Setting up multiple instances of the MySQL database server is straightforward and economical.

  Open-source distributions of MySQL have some stability and performance issues. It’s not designed to support exceptionally large databases or extremely intensive workloads. When using MySQL as a back-end database for large-scale web applications, you might experience a longer response time for complex queries. The lack of auto-sharding and auto-failover capabilities also makes the open-source version of MySQL unsuitable for distributed apps. It doesn’t support some standard SQL functions and relies on extensions to execute certain database operations. This often increases complexity for developers while migrating data from MySQL to other databases. Following the acquisition of MySQL by Oracle, the open-source developer community is experiencing a delay in the release of security patches and bug fixes. The uncertainty around the future direction of this edition is leading most developers to choose its fully compatible fork version, MariaDB.
• History of MySQL

  History of MySQL

  MySQL was created by Michael Widenius and David Axmark in 1995 and was initially released in 1996. It quickly gained popularity due to its open-source nature, ease of use, and robust performance. In 2001, MySQL AB, a Swedish company, was founded to support and develop the MySQL database. Key milestones include the release of MySQL 5.0 in 2005, which introduced stored procedures, views, and triggers, significantly enhancing its functionality. In 2008, Sun Microsystems acquired MySQL AB, and two years later, Oracle Corporation acquired Sun, thereby gaining control of MySQL. This acquisition led to concerns in the open-source community, prompting the creation of forks, such as MariaDB, by Michael Widenius. Oracle has continued to develop MySQL, releasing major versions such as MySQL 5.7 in 2015 and MySQL 8.0 in 2018, which introduced features including JavaScript Object Notation (JSON) support, improved performance, and enhanced security. These developments have solidified MySQL's position as a leading open-source database management system.
• SQL versus MySQL

  SQL versus MySQL

  • SQL: It is a standard programming language used for managing and manipulating relational databases. It provides a set of commands for creating, reading, updating, and deleting data in a database. SQL is not a database system itself but a language that can be used with various database systems, including MySQL, PostgreSQL, Oracle, and Microsoft SQL Server. Common SQL commands include SELECT, INSERT, UPDATE, and DELETE

  • MySQL: It is a specific RDBMS that uses SQL as its primary query language. It is one of the most popular open-source database systems, known for its reliability, performance, and ease of use. MySQL provides the infrastructure to store, retrieve, and manage data. It includes features such as transaction support, replication, and security mechanisms. MySQL is widely used in web applications, content management systems, and other data-driven applications

  In summary, SQL is the language used to interact with relational databases, while MySQL is a specific database system that implements and supports SQL. MySQL provides the environment and tools to manage data, whereas SQL is the language that allows you to perform operations within that environment.
• What Is MySQL Schema?

  What Is MySQL Schema?

  In relational databases, such as MySQL, a database schema defines the structure and organization of data within the database. In technical terms, the schema refers to the logical composition of database objects within MySQL database, used to store and manage information. It also functions as a data dictionary that contains information about various data objects, such as tables and indexes, in MySQL.

  Three default schemas are available in this open-source database:

  1. Information schema, which operates like metadata of MySQL
  2. Performance schema, which observes MySQL database server events and performance
  3. Sys schema, which relies on a pool of objects to decode the information captured by the performance schema
• User Interfaces and Tools

  User Interfaces and Tools

  Users can interact with MySQL through various tools, each catering to different needs and skill levels. GUIs such as MySQL Workbench, DBeaver, Navicat, and HeidiSQL provide user-friendly environments for database design, development, and administration. These tools provide visual query builders, data modeling capabilities, and schema management features, making them ideal for both beginners and experienced users. Web-based tools, such as phpMyAdmin, are particularly popular in web development environments, allowing users to manage databases and execute SQL queries directly through a browser.

  For more advanced and flexible interactions, command-line tools such as MySQL Shell and the MySQL client are essential. MySQL Shell supports multiple scripting languages and is well-suited for complex administrative tasks, while the MySQL client is a lightweight tool for quick database interactions. Third-party applications, such as Percona Toolkit, offer a collection of command-line tools for performance tuning and database maintenance. Additionally, MySQL Connector/ODBC enables applications to connect to MySQL databases using the ODBC standard, facilitating seamless integration with tools such as Microsoft Excel and Access. These diverse tools enable users to effectively manage and interact with MySQL databases in a manner that best suits their requirements.
