What relationship type would allow one record in a table to point to one record in another table?

One-to-one relationship type is characterized by the scenario where a record in one table corresponds directly to a single record in another table. In this context, the relationship implies that each entry in the first table can be linked to exactly one entry in the second table and vice versa. This relationship is typically established through the use of foreign keys, where the unique identifier of one table points to the unique identifier of another.

This relationship type is particularly useful in scenarios where two entities have a close association but are structured in separate tables for normalization purposes. For instance, you could have a table for employees and a separate table for employee details, where each employee has exactly one set of details; this would necessitate that each employee record in the first table is linked to exactly one record in the employee details table.

The other relationship types, such as many-to-many, foreign key, and composite key, serve different purposes:

• Many-to-many indicates that multiple records in one table can relate to multiple records in another, which does not apply to the prompt.

• Foreign keys refer to a constraint used to create relationships but do not define the type of relationship itself.

• Composite keys involve using multiple columns to uniquely identify a record in a table, which does not pert
