Relational Databases and Structured Query Language (SQL)

Relational databases are a type of database management system (DBMS) that organizes and stores data in a structured manner using tables with rows and columns. The relationships between these tables are defined based on common fields, fostering data integrity, and facilitating efficient retrieval and manipulation of information.

SQL (Structured Query Language) is the standard language used to interact with relational databases. It provides a set of commands for various tasks, such as creating and modifying database structures, querying data, and managing the content of databases. SQL enables users to perform operations like retrieving specific data, updating records, inserting new data, and deleting information, making it a crucial tool for database administrators, developers, and anyone involved in working with structured data.
