System Analysis & Design
- Interpret the object model for the new online storefront by responding to the following prompts:
- What are the different functions of the online storefront? How are they represented in this type of model?
- What are the different classes of “users” represented by this object model? What are the associations between these classes?
- How would the objects “use” their respective variables and functions?
- Does this object model capture all of Hamp Crafts’ desired functionality? Why or why not?
- The above diagram uses a solid diamond shape to represent a form of aggregation. What type of aggregation does this represent? What does it imply about the relationship between the classes? Why is a solid diamond the appropriate choice here?
- Finally, think through the two different models you’ve explored for Hamp Crafts’ systems: a process model and an object model. Then compare these models by responding to the following prompts:
- How well do you think a process model describes the system? What information does it make easier to understand? What aspects of the system are more difficult to understand or are not represented?
- How well do you think an object model describes the system? What information does it make easier to understand? What aspects of the system are more difficult to understand or are not represented?
