You are asked to design a software package for an On-line Banking System (OBS). The OBS will take requests from its user on the Internet. The requests include open an account with savings, checking, and CDs. Transfers between savings and checking in the same Bank, transfers between checking accounts in the different Banks, and Establish a CD are also among the requests. Close an account, or just close the savings account, withdraw CD are also permissible.Deposit, withdraw from a checking account are as routine requests. First and the most important is to understand the requirements as stated above (customers mission statement).In the OOD&A course, you were taught to go through steps as outlined below to design a system. To complete this exam, you are to carry out the following steps on the paper and e-mail your answer to me.

Step1. Identify the actors and the software entities for the system to be implemented.

Step2. Describe 7 Customer/Business Use Cases.

Step 3.Derive User Interface from the Business Use Cases. Draw a few user interface sketches.

Step 4.Draw a Use Cases Diagram which consists of 7 use cases defined in Step 2.Step 5. Create at least 7 to 9 Classes from Actors and Entities as you have defined in the use cases.

Step 6. Write attributes and Operations (Methods) for each Class. The Operations are derived from Activities in the system. For the Operations (Methods), no code is necessary just the name (declaration) of the Methods.

Step 7. Draw one Sequence Diagram with 5 to 7 entities as you defined in use cases. This is the Behavior Modeling. Draw communication diagrams for the Use cases you defined in Step 2 and 4. This step is called Use Case Realization.
