What kind of relationships does a Relational Model typically reflect?

The relational model, which forms the foundation for relational database management systems, primarily reflects one-to-many relationships. Each entity or table in this model can have a primary key, which uniquely identifies each record, and this primary key can be referenced in another table, creating a link between them. For instance, a customer can place multiple orders; here, the relationship between the customer (one) and their orders (many) exemplifies a one-to-many relationship.

This structure allows for efficient data organization and retrieval, as it keeps data normalized, reducing redundancy. Furthermore, SQL queries can easily navigate these relationships, making it straightforward to aggregate and report on data from multiple related tables.

While other relationship types, such as many-to-many and one-to-one, can exist within relational databases, the fundamental nature of the relational model emphasizes one-to-many relationships as its core. This is why the answer accurately reflects the characteristics of relational modeling in database design.
