Each department is identified with its name. For each department, the following data should also be stored: the number of floors, opening hour, and closing hour. Each department has a number of rooms. Each room is identified by its room number, but there might be rooms with the same name in different departments. At each department, many doctors and nurses can work.A doctor is…
Use ER Assistant to draw your diagram. Draw a self-referencing entity type for the Employee entity type for which an employee is supervised by a maximum of one other employee and doesn’t have to be supervised by any employee at all. Conversely, an employee can supervise zero or many other employees. The attributes of the Employee entity are as follows: EmpNo (primary key), EmpName, EmpAddress.
Build an entity-relationship diagram, deriving relations and validating relations using normalization up to third normal form
Consider the following entity relationship diagram. Booking Employee Room Building • Booking ID • Employee ID • Building ID • Room ID • First Name • Room ID P • Name Description • Employee ID • Name Last Name • Date • Campus Zone • Email Address • Capacity • Start Time • Map Coordinates Phone • Bookable • End Time For each statement below, use the drop-down box to indicate whether it is true (answer 1) or false (answer2), according to the design decisions encoded in the ERD. Every booking is associated with exactly one employee. ✓ Every employee is associated with at most one booking. ✓ A building may contain no rooms that are recorded in the database. Each room may have many bookings. 1. True ✓ A room must have at least one booking. 2. False ✓ A booking can be associated with many employees. An employee may have no phone number recorded. ✓ A room must have its capacity recorded. ✓ A building is uniquely identified by its map coordinates.
Make a UML diagram, Entity Relationship Model with the following data from the table
Is there a need for creating an associative entity? If so, draw one, if not, then suggest why?
Describe how functional dependencies may be used to show: • There is a many-to-one connection set between the entity sets student and instructor, as well as a one-to-one relationship set between the two.
1) Add a couple of attributes (including Primary keys) to each entity set. 2) Use Reification to transform it into a diagram with only binary relationships.
