The assignment requires creating a personnel system database for a government agency, focusing on database modeling and normalization. It involves developing an effective entity relationship model (ERM), identifying entities for data repositories, analyzing risks, and documenting each step of the normalization process. Specific formatting and content guidelines must be followed, including diagrams and a cover page.

1. Assignment 4: Database Modeling and Normalization
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

2. 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
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 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
