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?

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
Design a system to track advance payments made to employees. Use uml diagrams and design patterns in this system. The design steps will be as follows.
Step 1 - Prepare an analysis document on the given topic.
Step 2 - Create a Use case diagram for your requirement that contains at least 3 actor, 10 use case and use all relationship type
Step 3 - Create an activity diagram for requirement
Step 4 - Create a class diagram for all requirement that contains at least 10 class, necessary relations and types. Add the important attributes of the classes to the model.
Step 5 - Use three design patterns, at least one creation, one structural, and one behavioral pattern, integrated into your classroom design.
Step 6 - Code one of the design patterns you use with java.
Note: The design should be homogenate. Excessive usage of any property type, object type, or function type is not suitable. For example, for creating 10 relations between classes, the number of relation types for aggregation,…
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)

- Draw ER diagram for the following upload the diagram ?? A laboratory has several chemists who work on one or more projects. Chemists also may use certain kinds of equip- ment on each project. Attributes of CHEMIST include Em- ployee_ID (identifier), Name, and Phone_No. Attributes of PROJECT include Project ID (identifier) and Start_Date. Attributes of EQUIPMENT include Serial_No and Cost. The organization wishes to record Assign_Date-that is, the date when a given equipment item was assigned to a particular chemist working on a specified project. A. chemist must be assigned to at least one project and one equipment item. A given equipment item need not be as- signed, and a given project need not be assigned either a chemist or an equipment item.

[HINT: There are 3 entities and 2 relationships in the model answer]. A bus depot includes a maintenance section that repairs faulty buses. Each bus is identified by its fleet number, its make, the year it was manufactured and its registration number. When a vehicle breaks down, a report is submitted describing the nature of the problem and the time when the incident occurred. These reports are consecutively numbered as they are received and include the time when the bus was returned to the depot for repair. One or more mechanics fix the bus.
