Project Deliverable 3: Database and Data Warehousing Design

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 style conventions.

1. “Patterns of Behavior” Please respond to the following:

• Evaluate the patterns of behavior of early adapters versus followers. Determine the pattern of behavior that leads to a competitive advantage. Justify your response.
• Give your opinion as to whether “Heat Seekers” and “Followers” could coexist within the same organization. State the negatives and positives associated with both patterns of behavior.

2. “Getting to Know the Industry” Please respond to the following:

• Getting to know the industry in which a company operates is a critical factor for leveraging information systems and gaining a competitive advantage. Speculate as to how information systems can be leveraged in a particular industry. Analyze how time of entry, industry trends, corporate culture, and other factors affect competitive advantage. Explain your answer.
• Evaluate the competitive applications of technology. List and describe three applications and how these can be applied to the information systems industry.

3. “ITPM Best Practices” Please respond to the following:

• Explain how ITPM best practices can align the IT portfolio with business requirements in order to create the greatest possible value for the organization.
• Assess the systems development life-cycle (SDLC) and explain how the life cycle, when executed properly, can maximize business value. Note: All stakeholders point of view should be considered.

• Determine how a company’s selection of a Service Delivery Model could impact business value. Provide an example to justify your response.

5. “The New Beginning and Prototyping” Please respond to the following:

Computerized Operating Systems (OS) are almost everywhere. We encounter them when we use out laptop or desktop computer. We use them when we use our phone or tablet. Find articles that describes the different types of operating systems (Linux, Unix, Android, ROS, z/OS, z/VM, z/VSE, etc). Do not select MS WINDOWS. Write a scholarly review of comparing any two or more OS; attach a copy of the article to your postings. Remember, this assignment is to be scholarly; it is not enough for you to simply post your article and add cursory reviews. Cited references are required.
