History and Evolution

MySQL was first developed by Michael Widenius, Allan Larsson, and David Axmark in 1995 under the company MySQL AB. The initial goal was to provide a reliable and fast solution with an emphasis on open-source distribution. It quickly gained traction among developers due to its simplicity and Performance Optimization

. Key milestones in MySQL’s evolution include:
  • 1996: MySQL version 1.0 was released.
  • 2000: MySQL became fully open source under the GNU General Public License (GPL).
  • 2008: Acquired by Sun Microsystems.
  • 2010: Sun Microsystems (and by extension, MySQL database ) was acquired by Oracle Corporation.

Under Oracle, MySQL foreign keys continued to thrive, receiving significant updates and support. Variants like MariaDB were also created to preserve the open-source spirit. Ultimate Solution for Database Management ensuring that developers have multiple options based on their specific requirements.


Core Features

MySQL offers a rich set of features that make it an ideal choice for a broad range of applications:

  • ACID Compliance: Ensures reliability through atomicity, consistency, isolation, and durability.
  • Multi-User Support: Enables concurrent access by multiple users without data conflict.
  • Replication: Supports master-slave and master-master replication for scalability and fault tolerance.
  • Partitioning: Enhances performance by dividing tables into manageable pieces.
  • Stored Procedures and Triggers: Facilitates complex business logic directly within the database.

      Installation and Configuration

      Installing MySQL can be done through native packages or installers provided by Oracle. The process varies slightly depending on the operating system:

      On Windows:
      • Download and run the MySQL Installer.
      • Choose a setup type (Developer Default, Server Only, etc.).
      • Configure the server (port number, root password, user accounts).
      • Start the MySQL server and test using the MySQL Command Line Client or Workbench.

      Data Types and Storage Engines

      MySQL supports a wide variety of data types, grouped into categories:

      • Numeric Types: INT, BIGINT, DECIMAL, FLOAT, DOUBLE
      • Date and Time Types: DATE, TIME, DATETIME, TIMESTAMP
      • String Types: CHAR, VARCHAR, TEXT, BLOB
      • Spatial Types: GEOMETRY, POINT, LINESTRING
      • Storage engines determine how data is stored, indexed, and managed. Key storage engines include:

      • InnoDB: Default engine, supports transactions, row-level locking, foreign keys.
      • MyISAM: Legacy engine, fast for read-heavy operations but lacks transactions.
      • Memory: Stores all data in RAM for ultra-fast access, Buffer data is volatile.
      • CSV: Stores data in CSV format, useful for import/export.

      SQL Commands in MySQL

      MySQL supports a full range of SQL commands in MySQL categorized into Data Definition Language (DDL), Data Manipulation Language (DML), Data Query Language (DQL), and Data Control Language (DCL).

      DDL:
      • CREATE TABLE employees (id INT PRIMARY KEY, name VARCHAR(100));
      • ALTER TABLE employees ADD COLUMN salary INT;
      • DROP TABLE employees;
      DML:
      • INSERT INTO employees VALUES (1, ‘John Doe’, 50000);
      • UPDATE employees SET salary = 55000 WHERE id = 1;
      • DELETE FROM employees WHERE id = 1;
      DQL:
      • SELECT * FROM employees;
      • SELECT name FROM employees WHERE salary > 50000;
      DCL:
      • GRANT SELECT ON employees TO ‘user’@’localhost’;
      • REVOKE SELECT ON employees FROM ‘user’@’localhost’;
