Assignment 5: Tour Operator Agency Database
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:
   1. 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.
   2. Create naming conventions for each entity and attributes.
   3. 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 with which you are familiar. 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:
   1. Construct  a trigger that will increase the field that holds the total number of  tours sold per salesperson by an increment of one (1).
   2. 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 any chart or drawing tool with which you  are familiar. 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:

• Explain the fundamentals of how data is physically stored and accessed.
• Compose conceptual data modeling techniques that capture information requirements.
• Design a relational database so that it is at least in 3NF.
• Prepare  database design documents using the data definition, data manipulation,  and data control language components of the SQL language.
• Use technology and information resources to research issues in the strategic implications and management of database systems.
• Write  clearly and concisely about topics related to the strategic planning  for database systems using proper writing mechanics and technical style  conventions.
