be used to store student information generated by a web form. As an example, let us consider the
Student Club web page that uses the Table storage to store the information about club members.
he web page can be used for students to register for a club. his form will allow a student to
select a club that the student likes. To register for a club, the student needs to enter the contact
information. He or she can also upload his or her photo along with the contact information. After
the student clicks the Submit button, the form should display a message to welcome the new club
member and the contact information of the fellow club members. According to the description of
the form, we can identify the input and output shown in Table 11.3.
