- Relational databases use Structured Query Language (SQL) for data manipulation and retrieval.
- Popular relational database management systems (RDBMS) include MySQL, PostgreSQL, Oracle Database, and Microsoft SQL Server.
- Relational databases ensure data integrity, consistency, and support for complex queries and transactions.

- Normalization is a process in relational databases that organizes data to reduce redundancy and improve data integrity.
- ACID (Atomicity, Consistency, Isolation, Durability) properties are fundamental principles that ensure reliable processing of database transactions.
