Phase 1 revisions and alternate solutions

Revised Project description | Alternate solution to original project description (I) | Solution to revised project description (II)

Notes regarding the revised project description:

•  The changes in the project description are shown in red font.

Notes regarding the solutions:

• Return can be modeled according to any of the ways shown in above solutions. However, if it is modeled according to one in II, there must be a quantity associated with the relationship return.
• A subtle change to be noticed in II is that the customer can have multiple credit cards and credit cards can be used by multiple people. The example can be as follows: Son purchases using the credit card of his father. Since there is an option on the checkout screen to enter a new credit card information, son can enter details of his father's credit card.
• The revised solution is vey similar to the original solution posted about a month back.

Deliverables for phase 2:

• Go through the alternate solution above. If you feel you will get some points back, attach the original EER diagram and on a separate sheet mention if you need it to be re-graded along with places you feel you can get the points back.
• All other deliverables as mentioned in the project description.
• IMPORTANT: Mention section of each and every member of the team on the front sheet along with the name of the TA who graded your phase 1.
