SD2520 Introduction to Database and XML with jQuery Unit 4

Go through Chapter 5, pp. 80–98 in the textbook, Introduction to Database and XML with
jQuery. This chapter explores the importance of database design review and normalization.

Go through this module’s lesson, which explains how to review a given ERD.
Title: Reviewing an ERD
Read the following scenario on Wild Wood Apartments and think about the requirements of the
Wildwood Apartments database:
Wild Wood Apartments owns 20 different apartment complexes in Washington, Oregon, California, and
Idaho. Each apartment complex contains anywhere from 10 to 60 separate apartments of varying sizes.
All apartments are leased with a six-month or one-year lease.
It is the company’s practice to hire one of the tenants to manage each apartment complex. As managers, they need to admit new tenants to the building, collect rent from existing tenants, and close out leases. The manager also needs to maintain the apartments and conduct any repairs, replacements, or renovations. These can be billed back to the parent company. For acting as manager, the tenant gets free rent and a stipend. The stipend varies depending on the size of the apartment building.
Each manager is expected to send a report to the Wild Wood Apartments company headquarters in San
Francisco every quarter. This report summarizes the occupancy rate, the total revenues in rent, the total expenses in maintenance and repairs, and so on. Currently managers fill out a paper form and mail it back to headquarters. Many apartment managers have complained that preparing this report is a very difficult and time-consuming process. In addition, the managers at the corporate headquarters have expressed concern about the accuracy and verifiability of the reports.
To allay these concerns and to improve the ease and efficiency with which the apartment managers conduct their daily business, the company is proposing the development of a centralized database that the managers can use to track the daily business of their apartment building and to prepare their reports.
As a follow-up on your initial interview with the project coordinator, Wild Wood Apartments has agreed to show you some samples of the various forms and reports they use.
Design a database that is normalized to 3NF to guard against various types of anomalies.
Create a Visio file that shows the normalized database design and in a Microsoft Word document, explain the rationale for making your design. Describe how your design protects against insertion, deletion, and update anomalies.
Submission Requirements:

For this analysis, you need to submit the following files to your instructor: o The Word document titled “SD2520_Module 4_Analysis 4_1.docx” o The Visio file that shows the normalized design
Evaluation Criteria:
The analysis rubric will be used to evaluate this assessment. In addition, your submission will be evaluated against the following points:

Did you normalize your design to the first normal form?

Did you normalize your design to the second normal form?

SD2520 Introduction to Database and XML with jQuery Unit 4

Did you normalize your design to the third normal form?

Did you document the reason for each change, the normalization form that required it, and the anomaly it protects against?
LAB 4.1 (3.0 HOURS)
Assessment Preparation Checklist:
To prepare for this assessment:

Go through Chapter 5, pp. 80–98 in the textbook, Introduction to Database and XML with
jQuery. This chapter describes the importance of design review and normalization and examines how to evaluate an entity against the first three normal forms.

Go through this module’s lesson, which describes the process of normalizing an ERD.
Title: Normalizing an ERD
In this lab, you will review a given ERD and normalize it using Microsoft Visio.
Required Setup and Resources:

Windows XP (or later)

Microsoft Visio 2003 (or later)

Lab4_1starter.vsd
Recommended Procedure:
1.
Read the Westlake hospital scenario given below:
The start of the double-blind test is approaching rapidly. There is a great deal of pressure on you to begin building the actual database. Before you can do that, though, you must perform a final review to make sure that the database is normalized and complete.
2.
Launch Microsoft Visio on your lab computer. Note that Visio is installed on the host operating system, not on your virtual machine.
3.
Open Lab4_1starter.vsd. This file shows one table in the database design for the Westlake
Research Hospital scenario.
4.
Save Lab4_1starter.vsd as nnLab4_1solution.vsd, where nn are your initials.
5.
Normalize the PatientVisit table to the first normal form by referring to the Patient Visit form given below:
3

SD2520 Introduction to Database and XML with jQuery Unit 4
Notice that there are a number of predefined symptoms with checkboxes, as well as a field where the doctor can write symptoms that are not listed. This means that the Symptoms attribute might contain an array of values and violate the first normal form. One way to handle this would be to create a separate attribute for each symptom listed, but that still wouldn’t handle the possibility that the patient might have other symptoms. Therefore, a better solution is to create a separate entity named PatientVisitSymptoms. Next, perform the following steps: a.
Add an entity named PatientVisitSymptoms to the ERD. b.
Define the following attributes:
4

SD2520 Introduction to Database and XML with jQuery Unit 4 i.
PatientKey (PK) ii.
VisitDate (PK) iii.
Symptom c.
Add a relation that creates a one-to-many relationship between PatientVisit and
PatientVisitSymptoms. d.
Remove the Symptoms attribute from the PatientVisit entity.
Now, look at the DoctorNotes attribute. This attribute is one you would want to discuss with the client. If a doctor needs to enter multiple notes, it would be a good idea to normalize using a similar approach as for the Symptoms table. However, if a doctor’s note should be treated as a single field, you would want to leave it as is.
6.
Normalize the PatientVisit entity to normal form 2.
Can you see any functional dependencies in the entity? (HINT: In what circumstance would the
DropReason attribute not contain a value?) Next, perform the following steps: a.
Add a DroppedPatient entity that includes the following attributes to your ERD: i.
PatientKey ii.
DateDropped iii.
ReasonDropped b.
Add a one-to-one relationship between the DroppedPatient table and the Patient table. c.
Remove the ContinueOrDrop and DropReason attributes from the Patient Visit table.
7.
Normalize the PatientVisit entity to normal form 3.Are there attributes that do not relate to the primary key? What about DoctorName?
Remember, each patient is assigned a doctor, which is identified by DoctorKey in the Patients entity. Therefore, DoctorName is dependent on only PART of the primary key, not on the full primary key. Remove the DoctorName attribute from the PatientVisit entity.
Your normalized table should look like this:
