Textbook Question
Chapter 1, Problem 1.45PAE
Consider the project data model shown in Figure 1-16
- Create a textual description of the diagrammatic representation shown in the figure. Ensure that the description captures the rules/constraints conveyed by the model.
- In arriving at the requirements document, what aspect of the diagram did you find was the most difficult to describe? Which parts of the requirements do you still consider to be a little ambiguous? In your opinion, what is the underlying reason for this ambiguity?

Students have asked these similar questions
I'm designing an ER diagram for a project and I have to represent an entity called User, with the attributes: Username, Password and Role.
But the role contains (Supervisor and Farmer)
My question is should role be a multivalue property (attribute) or should it be two separate entities?
Either way, how would it be represented in the ER diagram? (if it was an attribute or two entities)
Design the Entity Relationship Diagram (ERD) showing entities, attributes, primary key and relationship cardinality for the
following scenario.
Any employee works for only a department and under supervision of a manager (where manager is also an employee).
Employee's address, city code & city name also has been recorded. Every employee may work for multiple project, but an
employee may be on vacation and not assigned to any projects. Working hour may be different for an employee for
different projects. Projects are broken into tasks; A task is created for one project and assigned to one department.
Requisitions are made for projects; Each requisition could ask for any number of items; Items could be: equipment item
or materials item and are coded in a similar way; Each requisition is for one project and is made to one supplier.
The important data fields are employee_id, employee_name ,employee_address, employee_email, department_id,
department_name, location, city_code, city_name,…
In this phase each student will select a real life problem that can be solved using database systems. Once you pick your project, start by writing a small description no more than 1 page to explain the project description. In this phase a project description is required only.
In this 2ND phase all you have to complete is preparing the UML diagram for the project that you have selected in Phase I
