Which of the following is not a type of relationship that can be applied in Access database :

The correct answer is All of the above.

Key Points

• In Microsoft Access, there are three primary types of relationships that can be defined between tables to establish a database structure. These are:
  • One to One: In this relationship, a row in one table is linked to a single row in another table. This type of relationship is not very common.
  • One to Many: This is the most common type of relationship. In this setup, a row from one table can be related to multiple rows in another table.
  • Many to Many: This relationship involves multiple rows in one table being related to multiple rows in another table. It is implemented using a junction table that contains foreign keys referencing the primary keys from the tables involved.

Additional Information

• All of the above relationship types (One to One, One to Many, Many to Many) are supported in Access database.
• Defining relationships correctly in Access is essential for ensuring data integrity and optimizing database performance.
• Relational databases like Microsoft Access use these relationships to organize and manage data efficiently.
• When setting up relationships, referential integrity can be enforced to ensure that relationships between tables remain consistent.
