Question 9

Relational databases are designed to store data in tables that can be logically joined together.

Relational databases allow for the organization of data into structured tables, which can be easily linked using relationships. This design enables efficient querying and data manipulation, making it ideal for applications where logical connections between data points are essential.

A) Hierarchical

Hierarchical databases organize data in a tree-like structure, where each record has a single parent and potentially many children. While this model allows for data relationships, it lacks the flexibility and ease of joining tables found in relational databases, making it less suitable for complex queries involving varied data connections.

B) Relational

Relational databases utilize a structured format where data is stored in tables, and relationships can be established through keys. This allows for sophisticated querying capabilities, making it easy to join tables based on logical relationships, which is precisely what the question describes.

C) Cloud

Cloud databases refer to database services hosted on cloud computing platforms. While they can include various database types, the term itself does not specify that the data is organized in tables that can be logically joined, which is a core requirement of the question.

D) Distributed

Distributed databases spread data across multiple locations or nodes to improve performance and availability. However, this term does not inherently imply that the data is organized in a way that supports logical joining of tables, as required by the question.

Conclusion

The relational database model is definitively the correct answer as it specifically addresses the need for data stored in tables that can be logically joined together. Other options either describe different structural paradigms or do not meet the specified requirements of the question.
