Complete the exercise and then using the finalized Use Cases and Conceptual Class diagram you created, design the system described.

Create the sequence diagrams and final implementation class diagram for the system

We are building a system to track personal finances. We plan an initial version with minimal functionality: tracking the expenditures. (Each expenditure has a description, date and amount.) We show below the use case for creating a new ex- penditure item and a new income item. Actor System (1) Inputs a request to create a new expendi- ture item (2) Asks for description, date, and amount (3) Supplies the data (4) Creates an expendi- ture item and notifies the user Actor System (1) Inputs a request to create a new income item (2) Asks for description, date, and amount (3) Supplies the data (4) Creates an income item and notifies the user (a) The use cases are quite weakly specified. In what ways? (Hint: Compare with the addition of a new member or book in the library system.) (b) What are the alternate flows in the use cases? Modify the two use cases to handle the alternate flows. (c) Identify the conceptual classes. We are building a system to track personal finances.
