Answer #1

The context diagram is also called the level 0 DFD.
It consists of:
– External entities.
– Data input to the system by the external entities,
– Output data generated by the system.

The functionalities that we can include in this software are:
- Adding a new contact or deleting a saved contact
- Should provide the details of the contact (address, email-id, phone-no.) if present
- Editing the details of a contact

Refer to the diagram below for level 0 DFD(Context diagram):

L details DED Level o Add/Delete Contact . updated :s list Contact Management Application contact name, - ei contact name jed

Note: More features also can be added. This is just a representation of a basic contact management application.
