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.

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.
•Be typed, double spaced, using Times New Roman font (size 12), with
instructions.
•Include a cover page containing the title of the assignment, the student’s
page length.
