Database and Data Warehousing Design
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.
The use of specific software has been suggested however equivalents including but not limited to OpenOffice, Dia, and Open Project are also permitted. If equivalent
tools are used, files must be saved and submitted for grading using extensions that are readable by their equivalent Microsoft Windows edition. Assignment submissions
that fail to follow this request may result in a reduced grade.
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 three page design document in which you:
a. Support the need for data warehousing within your company and elaborate on the best practices that the company will adhere to.
b. 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.
c. 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.
d. 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.
e. 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.
Section 2: Revised Project Plan
Use Microsoft Project to:
2. 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-
