Project Deliverable 3: Database and Data Warehousing Design
Due Week 5 and worth 110 points

This assignment consists of two (2) sections: a design document and a
revised project plan. You must submit both sections as separate files
for the completion of this assignment. Label each file name according to
the section of the assignment it is written for. Additionally, you may
create and / or assume all necessary assumptions needed for the
completion of this assignment.

One of the main functions of
any business is to be able to use data to leverage a strategic
competitive advantage. This feat hinges upon a company’s ability to
transform data into quality information. The use of relational databases
is a necessity for contemporary organizations; however, data
warehousing has become a strategic priority due to the enormous amounts
of data that must be analyzed along with the varying sources from which
data comes. Since you are now the CIO of a data-collection company which
gathers data by using Web analytics and operational systems, you must
design a solution overview that incorporates data warehousing. The
executive team needs to be clear about what data warehousing can provide
the company.

Section 1: Design Document

  1. Write a four to six (4-6) page design document in which you: 
    • Support the need for data warehousing within your company and elaborate on the best practices that the company will adhere to.
    • Create
      a schema that supports the company’s business and processes. Explain
      and support the database schema with relevant arguments that support the
      rationale for the structure. Note: The minimum requirement for the
      schema should entail the tables, fields, relationships, views, and
      indexes.
    • Create an Entity-Relationship (E-R) Diagram relating
      the tables of your database schema through the use of graphical tools in
      Microsoft Visio or an open source alternative such as Dia. Note: The
      graphically depicted solution is not included in the required page
      length but must be included in the design document appendix. Explain
      your rationale behind the design of your E-R Diagram.
    • Create a
      Data Flow Diagram (DFD) relating the tables of your database schema
      through the use of graphical tools in Microsoft Visio or an open source
      alternative such as Dia. Note: The graphically depicted solution is not
      included in the required page length but must be included in the design
      document appendix.
    • Illustrate the flow of data including both
      inputs and outputs for the use of a data warehouse. The diagram must map
      data between source systems, data warehouses and specified data marts.
      The diagram should map data between source systems, data warehouses, and
      specified data marts. Note: The graphically depicted solution is not
      included in the required page length.

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 MS Visio or Dia as an appendix of the design document. All
    references to these diagrams must be included in the body of the design
    document.

Section 2: Revised Project Plan

Use Microsoft Project to:

  1. Update
    the project plan from Project Deliverable 2: Business Requirements,
    with three to five (3-5) new project tasks each consisting of five to
    ten (5-10) sub-tasks.

The specific course learning outcomes associated with this assignment are:

  • Summarize how information systems represent a key source of competitive advantage for organizations.
  • Develop information systems-related activities to maximize the business value within and outside the organization.
  • Use technology and information resources to research issues in information systems.
  • Write
    clearly and concisely about strategic issues and practices in the
    information systems domain using proper writing mechanics and technical
