Which database model is characterized by using tables to represent data relationships?

The relational database model is characterized by its use of tables to represent data and the relationships between those data entities. In this model, data is organized into rows and columns, where each table corresponds to a specific entity and each row represents a unique instance of that entity. Relationships between the tables are established through the use of foreign keys, which help enforce data integrity and enable efficient querying.

This structure allows for a more flexible and organized way to store data, making it easier to retrieve and manipulate through structured query language (SQL). The relational model is widely adopted due to its ability to represent complex data relationships in a straightforward manner, facilitating normalization and minimizing data redundancy.

In contrast, other database models such as hierarchical, network, and object-oriented rely on different structures for representing data relationships. The hierarchical model organizes data in a tree-like structure, emphasizing parent-child relationships, while the network model uses a graph structure that allows for more complex relationships but can be more challenging to navigate. The object-oriented model integrates data and behavior, representing data as objects, which differs fundamentally from the table-based approach of relational databases. These differences highlight why the relational database model is the correct answer for the specific question about using tables to represent data relationships.
