                  Setting up Relationship

                  A relationship between two tables connects them through a common field. The field in the first
                  table is called the primary key, and the same field in the second table is called the foreign key.
                  The foreign key must match the primary key. To create this link, make sure both tables have a
                  primary key.

                  To create a relationship, create two tables:
                     Table named ‘Student's Detail’ that holds general information about the students, such as
                     their Roll No, Student's Name, Father’s Name, etc.
                     Table named ‘Fee’ that holds information about Roll No, Admn No and Fee_Status.










                  To define the relationship between the two tables, follow the given steps:


                                            1  Click on the Database Tools tab.


















                            2  Click on the Relationships command.    3  Click on the Add Selected Tables button.
