What is Banco de Dados Relacionais?

Relational databases are a type of database that stores data in tables (relations) with rows (tuples) representing records and columns (attributes) representing data fields. These databases use a structured query language (SQL) for data management and access. They are commonly used for managing structured data in a wide range of applications, including customer relationship management (CRM), inventory management, financial systems, and web applications, providing data integrity, consistency, and efficient data retrieval through defined relationships between tables.
