Break Down the Problem

1. Identify the type of databases mentioned in the options.
2. Determine which option describes a database structure with tables linked by common fields.

Relevant Concepts

• Centralized database: A single database located in one place, not necessarily involving tables or linking.
• Flat file database: A database that stores data in a single table or file without relationships.
• Relational database: A type of database that uses a structure that allows users to identify and access data in relation to another piece of data in the database.
• None of the above: Indicates that none of the previous answers fit the description.

Analysis and Detail

• In a relational database, data is organized into tables that can be linked through common fields (keys). This is essential for establishing relationships between different data sets.
• The other options do not introduce this linking capability.

Verify and Summarize

Since "relational database" is commonly defined as containing multiple tables linked through relationships, this matches the description provided in the question.

Final Answer

Relational database
