3. Relationships are links between the tables. Relationship works by matching data
in key fields (a field with the same name in both the tables). These matching
fields are the Primary key from one table and a Foreign key in other table.
Relationship between Tables
Foreign key is a value in one table that must match the Primary key in another table.
Example:- The given tables can be
linked using Roll No field.
 After creating relationships, you can create queries, forms and reports to display
information from several tables at once.
 After working with relationships, you must delete the relationship before you make
changes to the fields on which Relationship is based (Ex-Roll No fields).
 To delete relationships, select the Link line Press DELETE key. 3

7. Forms
A form resembles a fill-in-the-blanks sheet. It is a way to enter data into a database.
Access links the form to the table and stores the information of the form into the table.
 Data can be inserted, updated and deleted from a table using a form.
Three View of the Forms

(by default)
2) Layout View
