Database (2 Papers)
CIS 515 WEEK 3 ASSIGNMENT 3 UNIVERSITY 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.

Include charts or diagrams created in Excel, Visio, MS Project, or one
of their equivalents such as Open Project, Dia, and OpenOffice. The
completed diagrams / charts must be imported into the Word
assignment are:
Describe the role of databases and database management systems in
managing organizational data and information.
Recognize the historical development of database management
systems and logical data models.
Design and implement a database solution to solve a proposed
business problem.

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:
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.
