Develop a use case and DFD (Context Diagram and Level 0) for the New Party case. The case: A family which has many children (now adults, who have children of their own) want to make it simple and affordable by buying toys for each child in this party. They want to make it a fun experience, affordable, simple, and memorable. Add assumptions/clarifications that you like in this exam exercise, but make sure to address the main requirements listed below:

• You are to design a system that helps a large family with their Christmas gift exchange. Each year, Adult Siblings participate in the Family Christmas Gift Party for the children younger than 10 years old. A child must first select toys he/she wish to receive at the family party and put them in a list called Santas List. This list is a shared list where all Siblings can see what their nieces and nephews are wishing for. Each child must receive a toy from this Christmas party.
• Each Adult Sibling must buy as many toys as the number of their children. Adults need to check the Santas List in advance and notify the other Siblings if that bought certain toys (which fit their budget). If an Adult Sibling cant attend the Family Christmas Gift Party they must ship their present(s) in advance to the address where party will take place.
