DATABASE
Assignment 3: University Database
Due Week 3 and worth 90 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.

AGENCY DATABASE
Assignment 5: Tour Operator Agency Database
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:
1.Design a data model that will conform to the
following criteria:
a.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.
b.Create naming conventions for each entity and
attributes.
c.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 in Microsoft
Word or Visio, or an open source alternative such
as Dia. Note: The graphically depicted solution is
not included in the required page length.
2.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.
3.Using the salesperson table described in the
summary above, complete the following:
a.Construct a trigger that will increase the field
that holds the total number of tours sold per
salesperson by an increment of one (1).
b.Create a query that can produce results that
show the quantity of customers each salesperson
has sold tours to.
4.Support the reasoning behind using stored
procedures within the database as an optimization
process for the database transactions.

"Logical and Physical Design" Please respond to
the following:
In order to ensure optimal database performance,
the logical and physical design should consider the
user requirements thoroughly. Suppose you have
been hired to transform a conceptual model into a
logical model for a sales database. Describe the
specific steps that you must perform in order to
appropriately construct the database model. For
each step mentioned, speculate the risks that

would take place and how you would avoid or
mitigate those risks.
Suggest at least three activities that are required
in the physical design process of a database to
ensure adequate physical storage and data access.
Analyze why user, security groups, and role
definitions are essential to maintain the integrity
of the database.
