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.

The Driver enters constraints for a trip as a sequence of destinations. 2. Based on a database of maps, the planning service computes the shortest way of visiting the destinations in the specified order. The result is a sequence of travel segments concatenated together and a list of directions. 3. The Driver can revise the trip by adding or removing destinations.

Computer Science A programmer has the task of maintaining a database of students of a large university. There are two types of students, undergraduates and graduate students. All of the students have the same personal information stored, line name, address and courses taken. Each student's GPA is computed, but differently for undergraduates and graduates. The undergraduate have their declared program. The doctoral candidates have information about their dissertations and faculty advisors. Model an inheritance class hierarchy for this database. you are to consider what the common data is and what the unique data would be for each. Work with the details provided above. Just create the class definitions with the constructors and instance variables.
UML class diagramA hotel chain wants to model their hotels as a class diagram, with only certain aspects that matter, which are explained below: • A hotel has a location. It offers overnight stays and it offers meetings. • A hotel serves several guests. A guest's address is saved. • A hotel consists of several corridors and rooms. The most important characteristic of a hallway is its length, while that of a room is its square footage. • There are two specific types of rooms: rooms for overnight stays and meeting rooms for meetings.
