Assignment 4: Database Modeling and NormalizationÂ

Imagine  that you work for a consulting firm that offers information technology  and database services. Part of its core services is to optimize and  offer streamline solutions for efficiency. In this scenario, your firm  has been awarded a contract to implement a new personnel system for a  government agency. This government agency has requested an optimized  data repository for its system which will enable the management staff to  perform essential human resources (HR) duties along with the capability  to produce ad hoc reporting features for various departments. They look  forward to holding data that will allow them to perform HR core  functions such as hiring, promotions, policy enforcement, benefits  management, and training.

Using this scenario, write a three to four (3-4) page paper in which you:

  • Determine  the steps in the development of an effective Entity Relationship Model  (ERM) Diagram and determine the possible iterative steps / factors that  one must consider in this process with consideration of the HR core  functions and responsibilities of the client.
  • Analyze the risks that can occur if any of the developmental or iterative steps of creating an ERM Diagram are not performed.
  • Select and rank at least five (5) entities that would be required for the development of the data repositories. 
  • Specify the components that would be required to hold time-variant data for policy enforcement and training management. 
  • Diagram  a possible 1:M solution that will hold salary history data, job  history, and training history for each employee through the use of  graphical tools. 

    Note: The graphically depicted solution is not included in the required page length.

  • Plan  each step of the normalization process to ensure the 3NF level of  normalization using the selected five (5) entities of the personnel  database solution. Document each step of the process and justify your  assumptions in the process.
  • Diagram  at least five (5) possible entities that will be required to sustain a  personnel solution. The diagram should include the following: 

    Dependency diagrams
    Multivalued dependencies

    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 a drawing tool with which you are  familiar. The completed diagrams / charts must be imported into the Word  document before the paper is submitted.

    The specific course learning outcomes associated with this assignment are:

    • Recognize the historical development of database management systems and logical data models.
    • Explain the fundamentals of how data is physically stored and accessed.
    • Compose conceptual data modeling techniques that capture information requirements.
    • Use technology and information resources to research issues in the strategic implications and management of database systems.
    • Write  clearly and concisely about topics related to the strategic planning  for database systems using proper writing mechanics and technical style  conventions.
