Assignment 3: University Database
Due Week 3 and worth 120 points
A prestigious university has recently implemented a
consolidation strategy that will require it to centralize their
student records. In order to move forward, the local university
will need to develop a data model that will retain student
records and perform various data extract transform and load
(ETL) processes. Imagine that you have been hired as a
database consultant to assist in the development of a data design
strategy for the student records.
You met with various university subject matter experts and have
determined the following after performing various business
analysis processes:
Faculty groups are divided by core competencies that the
university offers. For example, there are groups such as the Art
Faculty, Computer Technology Faculty, Language Faculty, and
Science Faculty. Each faculty member has an assigned Dean and
is designated to teach at one particular campus and school. They
are able to teach as many courses as required.
Courses are categorized by course code and title. Certain
courses have prerequisites and the university has asked for this
to be cataloged as well.
There are various schools within each campus. For example, the
Los Angeles campus holds the following schools: School of
Science, School of Law, and School of Computer Technology.
Additionally, each school offers different professional study
programs such as Forensic Computer Science, Marine Biology,

Business Management, and Civil Engineering to name a few .
The study path for students requires that they be enrolled in a
specific professional study program. The professional study
program requires the students to complete a specific set of core
courses. The university also requires that an online grade book
be available. The online grade book should show grades
awarded to students for specific courses and the term they
completed the course.
The university identifies each student by his or her name, date
of birth, social, and professional study program.
Using these findings, write a three to four (3-4) page paper in
which you:
Analyze the university’s requirements and provide a proposal to
organize all the required data elements. The proposal should
include the following:
Provide an Entity Relationship Model (ERM) that will describe
the data structure that will store all data elements.
Note:
The graphically depicted solution is not included in the
required page length.
Describe any assumptions or limitations for each relationship.
For example, professors are able to teach more than one course
or students can only be enrolled in one program.
Create the primary key and foreign keys using a UML Class

diagram for each table.
Suggest at least four (4) types of business intelligence reports
that could help the university in course management, student
enrollment, or historical tracking. Support your answer by
providing specific business functions that these reports could
assist executives of the university.
As an alternative for development of the database, you are
considering outsourcing the functions above. Research the
Internet and other media sources for vendors who develop
registrar and school management database systems.
Suggest three (3) vendors that developed and are employing
efficient registrar and school management database systems and
support your reasons to choose from one (1) of these three (3)
vendors.
Compare and contrast the key aspects that each system offers.
Examples of system aspects include but not limited to cloud
based, pricing model, open source, etc.
Use at least three (3) quality resources in this assignment.
Note:
Wikipedia and similar Websites do not qualify as quality
resources.
Your assignment must follow these formatting requirements:
Be typed, double spaced, using Times New Roman font (size
12), with one-inch margins on all sides; citations and references

must follow APA or school-specific format. Check with your
professor for any additional instructions.
Include a cover page containing the title of the assignment, the
student’s name, the professor’s name, the course title, and the
date. The cover page and the reference page are not included in
the required assignment page length.
Include charts or diagrams created in any chart or drawing tools
with which you are familiar. The completed diagrams / charts
must be imported into the Word document before the paper is
submitted.

and technical style conventions.
Assignment 4: Database Modeling and NormalizationÂ

Imagine that you work for a consulting firm that offers
information technology and database services. Part of its core
services is to optimize and offer streamline solutions for
efficiency. In this scenario, your firm has been awarded a
contract to implement a new personnel system for a government
agency. This government agency has requested an optimized
data repository for its system which will enable the manageme nt
staff to perform essential human resources (HR) duties along
with the capability to produce ad hoc reporting features for
various departments. They look forward to holding data that
will allow them to perform HR core functions such as hiring,
promotions, policy enforcement, benefits management, and
training.
Using this scenario, write a three to four (3-4) page paper in
which you:
Determine the steps in the development of an effective Entity
Relationship Model (ERM) Diagram and determine the possible
iterative steps / factors that one must consider in this process
with consideration of the HR core functions and responsibilities
of the client.
Analyze the risks that can occur if any of the developmental or
iterative steps of creating an ERM Diagram are not performed.
Select and rank at least five (5) entities that would be required
for the development of the data repositories.Â

Assignment 5: Tour Operator Agency Database

The Strayer Oracle Server may be used to test and compile the
SQL Queries developed for this assignment. Your instructor
will provide you with login credentials to a Strayer University
maintained Oracle server.
A multinational tour operator agency has gained new business
growth in the North American market through the use of social
media. Its operation has expanded by 50% within six months
and the agency requires an enhanced data management strategy
to sustain their business operations. Their existing data
repository for its reservation processing system is limited in
business intelligence and reporting functionalities. The tour
operator seeks a database management specialist to assist them
in leveraging their data sources to enable them to forecast and
project tour sales appropriately.
Imagine that you have been hired to fulfill their need of
enhancing the data repository for their current reservation
processing system. Upon reviewing the system, you find that the
data structure holds redundant data and that this structure lacks
normalization. The database has the following characteristics:
A table that stores all the salespersons. The table holds their
employee id, first name, last name and “Tours sold” field. The
“Tours sold” field is updated manually.
A table that stores tour customer data and tours sold. The table
holds customer name, address, city, state, zip code, tour(s)
selected, number of persons in tour, and total amount paid. The
current structure will show the customer more than once, if the
customer books multiple tours.
A tour table that is used as a tour rate sheet which holds the
tours offered and the cost per person. Tour rates vary every
three (3) months depending on the tourist season.

Write a three to four (3-4) page paper in which you propose an
enhanced database management strategy. Your proposal should
include the following:
Design a data model that will conform to the following criteria:
Propose an efficient data structure that may hold the tour
operator’s data using a normalization process. Describe each
step of the process that will enable you to have a 2nd Normal
Form data structure.
Create naming conventions for each entity and attributes.
Conclude your data model design with an Entity Relationship
Model (ERM) that will visually represent the relationships
between the tables. You may make use of graphical tools with
which you are familiar.
Note:
Construct a query that can be used on a report for determining
how many days the customer’s invoice will require payment if
total amount due is within 45 days. Provide a copy of your
working code as part of the paper.
Using the salesperson table described in the summary above,
complete the following:

Construct a trigger that will increase the field that holds the
total number of tours sold per salesperson by an increment of
one (1).
Create a query that can produce results that show the quantity of
customers each salesperson has sold tours to.
Support the reasoning behind using stored procedures within the
database as an optimization process for the database
transactions.
Include charts or diagrams created in any chart or drawing tool
submitted.
