SQL, or Structured Query Language, is a domain-specific language used for managing and manipulating relational databases. It is employed for tasks such as querying data, defining and modifying database structures, and controlling access to the stored data.
SQL supports several fundamental operations, including SELECT (retrieve data), INSERT (add new data), UPDATE (modify existing data), DELETE (remove data), and CREATE/ALTER/DROP (manage database structure).
SQL is a language, while MySQL is a relational database management system (RDBMS) that uses SQL. MySQL is one of many database systems that implement the SQL language. Other examples include PostgreSQL, SQLite, and Microsoft SQL Server.
A primary key in SQL is a unique identifier for a record in a table. It ensures each row has a distinct identity, and it is often used to establish relationships between tables. The primary key constraint enforces the uniqueness and non-null properties of the key.
Normalization is the process of organizing data in a database to reduce redundancy and dependency. It involves dividing large tables into smaller, more manageable tables and defining relationships between them. Normalization helps maintain data integrity and avoids data anomalies.
