Project Homework: Database and Data Warehousing Design
This homework consists of two sections: a design document and a revised project plan. You must submit both sections as separate files for the completion of this homework. Label each file name according to the section of the homework it is written for. Additionally, you may create and / or assume all necessary assumptions needed for the completion of this homework.
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 I: Design Document
Write a 4 to 6 pages 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.
Section II: Revised Project Plan
Use Microsoft Project to:
• Update the project plan from Project Business Requirements, with 3 to 5 new project tasks each consisting of 5 to 10 sub-tasks.
Format your homework according to the give formatting requirements:
• The answer must be using Times New Roman font (size 12), double spaced, typed, with one-inch margins on all sides.
• The response also includes a cover page containing the student's name, the title of the homework, the course title, and the date. The cover page is not included in the required page length.
• Also include a reference page. The references and Citations should follow APA format. The reference page is not included in the required page length.
The specific course learning outcomes associated with this homework 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 style conventions.
