Which database structure is characterized by organizing data into tables that consist of rows (records) and columns (fields), and often uses keys to establish relationships between tables?
Relational databases
Key/value databases
Document databases
Non-structured data repositories
A relational database is a type of database that organizes data into tables. Each table is made up of rows, also known as records, which represent individual entries, and columns, also known as fields, which represent the attributes of those entries. Primary keys uniquely identify each row in a table, and foreign keys are used to establish relationships between different tables. This structure allows for organized data storage, efficient querying, and the ability to maintain data integrity. In contrast, key/value databases store data in simple key-value pairs, and document databases store data in flexible, document-like structures such as JSON.
