SQL (Structured Query Language) and MySQL are related but distinct entities. SQL is a standardized language for managing and manipulating relational databases, while MySQL is a specific relational database management system (RDBMS) that uses SQL. Here are five key differences between SQL and MySQL:
1. Definition:
SQL:
Definition: SQL, or Structured Query Language, is a standardized programming language used for managing and manipulating relational databases. It provides a set of commands for creating, retrieving, updating, and deleting data in a relational database management system.
MySQL:
Definition: MySQL is a specific relational database management system (RDBMS) that uses SQL as its query language. It is an open-source database system developed, distributed, and supported by Oracle Corporation.
2. Type:
SQL:
Type: SQL is a language, not a specific database management system. It serves as a standard language for interacting with various relational database systems, including MySQL, PostgreSQL, SQLite, Microsoft SQL Server, and others.
MySQL:
Type: MySQL is a relational database management system. It is a specific software implementation of a database system that uses the SQL language for querying and managing databases.
3. Compatibility:
SQL:
Compatibility: SQL is a standardized language, and the syntax and basic commands are consistent across different database systems. However, there may be variations and extensions specific to each database management system.
MySQL:
Compatibility: MySQL follows the SQL standard, but it also includes some proprietary extensions and features that are specific to MySQL. While many SQL commands can be used in MySQL, there are MySQL-specific commands and functionalities.
4. Usage:
SQL:
Usage: SQL is used as a query language for interacting with relational databases. It is not a standalone database system but a language that can be employed with various database management systems.
MySQL:
Usage: MySQL is used as a relational database management system. It provides the infrastructure for creating, managing, and interacting with databases using the SQL language. MySQL is often used for web applications and other data-driven applications.
5. Ownership:
SQL:
Ownership: SQL is a language standard owned and maintained by the American National Standards Institute (ANSI) and the International Organization for Standardization (ISO).
MySQL:
Ownership: MySQL was originally developed by a Swedish company called MySQL AB, which was later acquired by Sun Microsystems and subsequently by Oracle Corporation. It is now owned and maintained by Oracle Corporation.
In summary, SQL is a standardized language for managing relational databases, while MySQL is a specific relational database management system that implements SQL. MySQL follows the SQL standard but includes some proprietary extensions specific to its implementation. SQL can be used with various database systems, but MySQL is a specific software product.
