Question

First Drawing Assignment:

Draw as complete a Class diagram as you can for the following possible application. We wish to BUILD A SOCIAL NETWORKarrow-10x10.png for COMPUTERarrow-10x10.png Science graduate students. This network will allow any graduate student to login and logout. Once logged in, the student may do any of the following: 1. Join a group of fellow students 2. Leave a group of fellow students 3. Create a group which fellow students may join if they wish. Creating a group involves naming that group and providing a brief description of the purpose of the group. 4. Read the messages in a particular group along with any comments associated with each of those messages 5. Save any specific message in a group to the student's computer 6. Add a new message to a group to which this student already belongs 7. Delete a message that the student created earlier. A deleted message also deletes any comments associated with it. 8. Add a comment to an existing message in a group to which the student belongs 9. Create an anonymous message which does not have the student's identity associated with it. Students are limited to having only up to ten such messages active at any time. The application must enforce this constraint at all times by not allowing a student to create another anonymous message, if their quota of ten active messages is reached until they delete at least one of the anonymous messages they created earlier or make it non-anonymous. In addition, all messages that are more than one semester old are deleted by the application. All messages that contain non-English words or profanity are deleted by the application. Add any supplementary text you feel is needed to make the intent of your diagram clear. In particular, you will be graded on how clearly your diagram expresses a design for satisfying each of the items above.

Second Drawing Assignment:

Do as complete a Use Case Diagram as you can for the application described in the first assignment. If your diagram becomes too complicated, partition it into multiple use case diagrams. Then select three of your use case scenarios to do either sequence diagrams or activity diagrams for each.

First Evaluation Assignment:

Use the Main Sequence ARCHITECTURAL DESIGN Metrics discussed in class to evaluate the architectural design you produced for the Drawing UML assignments. Show your work and be as specific as you can. The Architectural Design is the Class Diagram without the internals of each class beyond the public methods. If you are taking this class distance, the article below this assignment explains the main sequence and the metrics you should use.

First Construction Design Assignment:

One of the applications that is likely to be very important in the evolving Internet of Things is a SMART PHONE APP that receives information through Bluetooth and Wifi from the various intelligent devices and presents that information to the user. It is vital that the information be presented in a clear, easily understood manner even though many devices might wish to communicate with the user near simultaneously. Communications could be warnings, information, or status reports for the device. For example, a video camera in a server room might send the user warnings of fire, overheating, or an intruder in the server room. That camera might send the user information such as a current image of the room or a closeup of the screen of one or more of the servers within the room. That camera might send the user status reports, say every thirty minutes indicating that the camera is working, has a battery that is running out of power, is overheating, or is in a dormant state. You are to develop a construction design including data structure(s), interface(s), and algorithm(s) for the module that organizes the active messages into the three categories by device for subsequent display by another module. Justify your choices of data structure, interface, and algorithm.
