- Course: Database Systems: Design and Application Web Shop scenario: A supplier (Supp-#) processes many purchase orders (PO-#) and sells a number of products (Prod-#). A product is sold by only one supplier. Each of the purchase orders that a supplier may process includes several products. The relationship between order and product is defined as "Line Item". A customer (Cust-#) may place one or more purchase orders. A purchase order may be placed by only one customer. Assignment requirements: Answer the following questions using above scenario: Identify the entities and attributes that required to draw the ER diagram. Integrate the entities with appropriate relationship and design the unified ER model.Question 4 This question assesses Block 2 Part 4. Parts a and b of this question involve creating drawings or descriptions. You can make your drawings whichever way is easiest or fastest for you. For instance, you could simply make your drawings using pencil and paper then scan or photograph them. Alternatively, you can answer by providing descriptions of the drawings. In that case, keep close to the formulations used in the long figure descriptions of the examples given in Section 4.5 of Block 2 Part 4. a.Consider the following lines entered on the Python shell: >>> Q4_TMA02 = 'submitted' >>> id(Q4_TMA02) 1944127298928 >>> type(Q4_TMA02) >>> Q4_TMA02 'submitted' Draw (or describe) the object and its label that the Python interpreter creates in response to the assignment Q4_TMA02 = 'submitted' in the interactive shell above.

- You may define "cursor" in your own unique way.Q No. 2: Draw a Use Case diagram for "The Pizza Ordering System". (Hint – correct > or > relationships will attract additional marks). The Pizza Ordering System The Pizza Ordering System allows the user of a web browser to order pizza for home delivery. To place an order, a shopper searches to find items to purchase, adds items one at a time to a shopping cart, and possibly searches again for more items. When all items have been chosen, the shopper provides a delivery address. If not paying with cash, the shopper also provides credit card information. The system has an option for shoppers to register with the pizza shop. They can then save their name and address information, so that they do not have to enter this information every time that they place an order.SUNSHINE AIRLINE COMPANY The ER Diagram for the SUNSHINE AIRLINE COMPANY is based on the following: - For each airplane type, we keep track of a unique airplane type ID (AirplaneTypelD), number of engines (NoOfEngines), and number of seats (NoOfSeats). - For each airport, we keep track of a unique airport ID (AirportID), and the length of the main runway (LengthOfRunway). - Each airplane type is able to land at one airport at least, but may be able to land at many airports. Each airport accommodates landing of at least one airplane type, but may accommodate landing of more airplane types.
