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).
