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 transform data into information. The use of relational databases and data warehousing has gained recognition as a standard for organizations. A quality database design makes the flow of data seamless. The database schema is the foundation of the relational database. The schema defines the tables, fields, relationships, views, indexes, and other elements. The schema should be created by envisioning the business, processes, and workflow of the company. Since your company is an innovative Internet-based company, movement toward data warehousing seems to be one of the most viable options to give your company a competitive advantage; however, these concepts must be explained to the executive board in a manner to garner support.

Section 1: Design Document

  1. Write a six to eight (6-8) page      design document in which you:


  1. Support       the need for the use of relational databases and data warehousing. From a       management standpoint, it may be important to show the efficiencies that       can be gained for executive oversight.
  2. Create a       database 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.
  3. Identify       and create database tables with appropriate field-naming conventions.       Then, identify primary keys and foreign keys, and explain how referential       integrity will be achieved. Normalize the database tables to third normal       form (3NF).
  4. Identify       and create an Entity-Relationship (E-R) Diagram relating the tables of       the 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 the E-R Diagram.
  5. Identify       and 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. Explain the       rationale behind the design of your DFD.
  6. Illustrate       the flow of data including both inputs and outputs for the use of a data       warehouse. The diagram should map data between source systems,       operational 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.
