Q1. 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, 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). pg. 2 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 you hand in. Step1. Identify the actors and the software entities for the system to be implemented. Step2. Describe five 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 Case Diagram, which consists of five use cases, defined in Step 2. (use Visual_Paradigm software) is preferred or similar tool can be used. Step 5. Create at least 7 to 9 Classes from Actors and Entities as you have defined in the use cases. (use Visual_Paradigm software) is preferred or similar tool can be used. Step 6. Write attributes and Operations (Methods) for each Class. The Operations are derived from Activities in the system. (use Visual_Paradigm software) is preferred or similar tool can be used Step 7. Draw one Sequence Diagram with 5 to 7 entities as you defined in use cases. This is the Behavior Modeling. (use Visual_Paradigm software) is preferred or similar tool can be used. Draw communication diagrams for the Use cases you defined in Step 2 and 4. This step is called Use Case Realization. (use Visual_Paradigm software) is preferred or similar tool can be used. Step 8. Now you are at System Design Stage to make technology, and topology choices. (extra credit) The last step in this exam: Based on the answers for Step 5 and 6, write the Java code for class declaration, variable and method declaration, and Main.
