Which of the following describes the types of relationships in a database?

The option that describes the types of relationships in a database accurately includes one-to-one, one-to-many, and many-to-many relationships. These relationships are fundamental concepts in database design and management that dictate how different entities interact with each other.

A one-to-one relationship implies that for each record in one table, there is one and only one corresponding record in another table. This is useful in scenarios where two entities are closely linked, for example, in personal information databases where one person is associated with one user account.

A one-to-many relationship indicates that a single record in one table can be linked to multiple records in another table. This is a common relationship type used when, for instance, a single customer can place multiple orders. Here, one customer record relates to multiple order records.

Many-to-many relationships mean that records in one table can relate to multiple records in another table, and vice versa. Such relationships often require a junction table to organize the associations. An example would be students and courses, where a student can enroll in multiple courses, and each course can have multiple students.

Understanding these three types of relationships is essential in creating well-structured databases that allow for efficient data retrieval and integrity. The other options limit the scope of relationships in a database
