What type of database contains more than one linked table?

A relational database is specifically designed to organize data into multiple logically related tables. Each table can store different yet related information, and relationships between the tables can be established using primary and foreign keys. This structure allows for more complex data models, facilitating efficient data management and retrieval through the use of SQL (Structured Query Language).

In relational databases, you can easily perform operations that involve multiple tables, such as joins, which enable you to combine data from these linked tables based on established relationships. This capability is essential for applications that require a normalized structure to avoid redundancy and improve data integrity.

While hierarchical databases organize data in a parent-child structure and flat file databases store data in a single table format, they do not offer the same relational benefits of linking multiple tables. NoSQL databases often store unstructured or semi-structured data and do not rely on a fixed schema, which can lead to difficulty in managing relationships between data sets in the same way as relational databases. Therefore, the nature of relational databases to have more than one linked table is what defines them and makes them the correct choice for this question.
