What type of database structure uses tables composed of rows and columns to organize data, and often utilizes keys to establish relationships between different pieces of data?
Relational database

A relational database uses a structured format to organize data into tables that consist of rows (also known as records) and columns (also known as fields). This arrangement allows for the use of primary keys to uniquely identify each row and foreign keys to create relationships between tables, which is essential for maintaining data integrity and enabling complex querying.
