Also asked, what is relationship database?
A relationship, in the context of databases, is a situation that exists between two relational database tables when one table has a foreign key that references the primary key of the other table. Relationships allow relational databases to split and store data in different tables, while linking disparate data items.
Also, how do you create a relationship in access? You define a relationship by adding the tables that you want to relate to the Relationships window, and then dragging the key field from one table and dropping it on the key field in the other table.
Subsequently, one may also ask, how many types of relationships are there in access?
Why are relationships important in a database?
A logical relationship exists between the data in the STUDENTS table and the data in the STUDENT INSTRUMENTS table. It helps to further refine table structures and minimize redundant data. As you establish a relationship between a pair of tables, you will inevitably make minor modifications to the table structures.
