Overview
Object modeling is an important part of system
analysis and design. Since object-oriented languages such as Java and
C++ have become more common, systems analysts also need to be able to
design a system from an object-oriented perspective. Object modeling
involves thinking about the objects and classes that will be a part of
the final system. In an object-oriented approach, the focus is on
capturing the structure and behavior of information systems into small
modules that combine both data and process. The goal for using
object-oriented design (OOD) is to improve the quality and productivity
of system analysis and design by making it more usable.
In this
assignment, you are asked to evaluate an object model for the same
scenario you explored in Module Three. You will be given an object model
for the new online storefront. You will be asked to interpret the
diagram and evaluate how well it fits the scenario. Your work on this
assignment will help support your work on the module application short
paper for Project One.
Prompt
Hamp Crafts is a
family-owned craft store that has been in business for decades. Its
current operations are limited to its physical (brick-and-mortar)
storefront. Recently, the owners have determined that one of the best
ways to gain additional revenue is through online sales. You have
reassured Hamp Crafts’ owners that adding in an online storefront will
work with their current processes. In this assignment, you will review
an object model, specifically a UML class diagram for the new online
store. You will interpret the diagram and reflect on how well it meets
Hamp Crafts’ needs.
First, review Hamp Crafts’ needs for
their online storefront. Then review the UML class diagram for the new
online storefront. A version with alternative text is also available: Module Four Online Shopping Cart Object Diagram With Alternative Text.
Hamp
Crafts would like customers to be able to create an account with their
shipping, billing, and contact information. For customer orders, Hamp
Crafts would like to accept credit and debit cards for transactions.
Hamp Crafts plans on using an established credit card vendor service
(e.g., Square, Shopify) to receive customer payments. Once a transaction
is complete, the customer should receive a notification based on the
information in their personal profile regarding order status and
confirmation. On the administrative side of the online storefront, Hamp
Crafts should receive an alert of the transaction. Customers should be
able to check the status of their order any time online from their
personal account profile under order history. The business owners also
need an administrative back end for customer support and updates to
customer information and the website.
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?
