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 streamlined 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 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 and 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 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
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
entities of the personnel database solution. Document each step of the process and justify your assumptions in
the process.
Diagram at least five possible entities that will be required to sustain a personnel solution. (Note: The
graphically depicted solution is not included in the required page length.) The diagram should include the
Dependency diagrams.
Multivalued dependencies.
