Which of the following is used to associate entities with one another?

Explanation

In a relational database, entities are represented by tables. A relationship describes the connection between these tables. It specifies how data in one table relates to data in another table. There are three main types of relationships:One-to-one: A one-to-one relationship exists between two tables when a single record in one table corresponds to exactly one record in the other table, and vice versa.One-to-many: A one-to-many relationship is the most common type of relationship. In this type of relationship, a single record in one table (the "one" side) can be related to multiple records in another table (the "many" side).Many-to-many: A many-to-many relationship exists between two tables when a single record in one table can be related to multiple records in the other table, and vice versa. This type of relationship is typically implemented using a junction table.
