SQL (Structured Query Language):
SQL is a domain-specific language used for managing and manipulating relational databases. It is a standardized language for relational database management systems (RDBMS) and is used to perform various operations such as querying, inserting, updating, and deleting data in a database.
Here are some key points about SQL:
- Standardized Language: SQL is a standardized language, meaning it follows a set of rules and conventions defined by the American National Standards Institute (ANSI).
- Not Tied to a Specific Database System: SQL is not tied to any specific database system. It can be used with various types of database systems like MySQL, PostgreSQL, SQLite, Oracle, Microsoft SQL Server, etc.
- Declarative Language: SQL is a declarative language, which means you specify what you want to achieve, rather than specifying how to achieve it. For example, in a query, you specify the data you want to retrieve, but not how to retrieve it.
MySQL, on the other hand, is a specific implementation of an RDBMS that uses SQL as its query language. It is one of the most popular open-source database systems in the world.
Here are some key points about MySQL:
- RDBMS Implementation: MySQL is an actual relational database management system. It is a software program that manages databases based on the relational model.
- Developed by Oracle: MySQL was originally developed by a Swedish company called MySQL AB, which was later acquired by Sun Microsystems, and then by Oracle Corporation.
- Supports SQL: As an RDBMS, MySQL uses SQL as its query language. This means that you interact with MySQL using SQL commands for tasks like querying, inserting, updating, and deleting data.
SQL is a language used to interact with relational databases, while MySQL is an actual relational database management system that uses SQL as its query language. MySQL is one of many RDBMS options available, and it’s known for being fast, reliable, and widely supported in the development community.
