maintained Oracle server.
Imagine that you have been hired as the database administrator for a local department
store. The department store has recently expanded by opening five (5) stores within your
local region. They have also launched a series of marketing campaigns to attract new
customers and increase sales. For your hired role, you will be responsible for creating and
maintaining an enterprise-wide database system that will hold the sales and inventory data
for the organization. The designed database will help operations in supporting its new
business marketing strategy. Using the concepts presented throughout the course, you will
develop a plan to create this database and establish a design that aligns with the product
sales initiatives of the organization.
 Write a twelve to fifteen (12-15) page paper in which you:
 Identify the potential sales and department store transactions that can be stored
within the database.
 Design a database solution and the potential business rules that could be used to
house the sales transactions of the department store.
 Evaluate all relationships of each entity within your database solution using the
Crow’s Foot notation. Include all data elements, entities, relationships (such as 1:M,
1:1, M:N), and cardinalities for the department store database in your
diagram. Note:The graphically depicted solution is not included in the required page
length.
 Research the Internet for best practices of how retail stores use databases for
retaining customers and increasing sales and complete the following:
o Justify how Big Data tools could be used for forecasting sales and inventory of
the department store.
o Propose two (2) SQL Stored Procedures that use SQL functions to help sales
associates perform explanatory or predictive analytics.
o Give your opinion on which of the two (2) ways you proposed in Question four
(4) b provide greater value to expanding their business within the region.
o Provide a copy of your working SQL code as part of the paper.
 Research the Internet for database vendors that provide cloud computing services
and complete the following:
o Estimate the types of costs involved or the pricing structure required when
implementing a cloud-hosted solution for a database.
o Analyze security considerations and pricing of the different cloud
implementation types.
o Rank the cloud services options of Software as a Service, Platform as a Service
and Infrastructure as a Service in terms of functionality, mobility, and ability
to provide distributed transaction concurrency. Compare how these cloud-

based services fit within an environment where users are mobile. Determine
the technical provisions that would be required to ensure data integrity.
Evaluate whether the use of a distributed DBMS structure is appropriate and identify
the optimization techniques that should be factored in to enhance the operations of
the database in your design.
Provide at least two (2) examples of how lost updates and uncommitted data may
occur, keeping in mind that five (5) stores will be generating transactions.
Determine the concurrency control factors that can be used to ensure valid execution
of transactions within the current multiuser environment.
Research the Internet for backup and restoration recovery solutions and database
security threats that could be applicable to the department store. Upon your
research, complete the following:
o Suggest at least two (2) options that could be made available to provide
disaster management functions for the database system within the retail
environment.
o Assess the types of security threats that may exist when managing the
department store database and suggest measure(s) that can be performed to
minimize these threats that are particular to retail.
Use at least six (6) quality resources in this assignment. Note:Wikipedia and similar
Websites do not qualify as quality resources.

CIS 515 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 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:
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.
3.
Support the reasoning behind using stored procedures within the database as an optimization
process for the database transactions.
CIS 515 Assignment 6 SQL Concepts and Database Design – A Graded Paper

The Strayer Oracle Server may be used to test and compile the SQL Queries developed for this assignment. Your
