Answer
Yes, the states of both the relations are equivalent as the order of rows and columns does not matter and data is just the same in both the relations.

A school has a rule that each student must participate in a sports activity. So each one should give only one preference for sports activity. Suppose there are five students in a class, each having a unique roll number. The class representative has prepared a list of sports preferences as shown below. Answer the following:
Table: Sports Preferences
Roll_no Preference 9 Cricket 13 Football 17 Badminton 17 Football 21 Hockey 24 NULL NULL Kabaddi - Roll no 24 may not be interested in sports. Can a NULL value be assigned to that student’s preference field ?
- Roll no 17 has given two preferences in sports. Which property of relational DBMS is violated here ? Can we use any constraint or key in the relational DBMS to check against such violation, if any?
- Kabaddi was not chosen by any student. Is it possible to have this tuple in the Sports Preferences relation ?
The school canteen wants to maintain records of items available in the school canteen and generate bills when students purchase any item from the canteen. The school wants to create a canteen database to keep track of items in the canteen and the items purchased by students. Design a database by answering the following questions:
(a) To store each item name along with its price, what relation should be used? Decide appropriate attribute names along with their data type. Each item and its price should be stored only once. What restriction should be used while defining the relation ?
(b) In order to generate bill, we should know the quantity of an item purchased. Should this information be in a new relation or a part of the previous relation ? If a new relation is required, decide appropriate name and data type for attributes. Also, identify appropriate primary key and foreign key so that the following two restrictions are satisfied:
- The same bill cannot be generated for different orders.
- Bill can be generated only for available items in the canteen.
