NIIT

I would like to acknowledge the contributions of my Lecturer Mr. Lahiru Ratnayake to the development of my project & presentation.

Mr. Lahiru Ratnayake directed me to a wide range of resources on the web. He answered all of my questions as well as asked me questions that helped me to narrow my search. Further, He helped me figure out correct documentation for sources that did not fit the Research Guide examples. He gave me this help during class time and after class. I also worked with students at NIIT who helped me locate primary sources.

In the Time Card Expenses table the Expense Code depends on Expense Code ID not on Time Card Expense ID. Therefore, for the tables to be in 3 NF, we need to create another table, Expenses.

Also in the Invoice table, the attribute Payment Mode Name depends on Payment Mode ID and not on Payment Code. Therefore, we need to create a separate table Payment Modes.

In addition, the attributes Card Holders Name and Expiry Date of Card depend on Card Number not Payment Code. Therefore we need to create another table Credit Cards.

The updated table structures are shown here.

When we place the information about credit card in a separate table, the query performance during the generation of payment receipt will get affected due to creation of joins in every payment receipt. Therefore, for optimum performance, we denormalize and place the credit card information back into the Invoice table. The updated table structures are shown here.
