Tour Operator
Assessment Brief
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 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. 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. 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.
