Week 6 and worth 90 points
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:
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.
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 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 document before the paper is submitted.
The specific
course learning outcomes associated with this assignment are:
4.
Explain the fundamentals of how data is physically stored and accessed.
5.
Compose conceptual data modeling techniques that capture information
requirements.
6.
Design a relational database so that it is at least in 3NF.
7.
Prepare database design documents using the data definition, data manipulation,
and data control language components of the SQL language.
8.
Use technology and information resources to research issues in the
strategic implications and management of database systems.
9.
Write clearly and concisely about topics related to the strategic
planning for database systems using proper writing mechanics and technical
style conventions.
