This document outlines an assignment for a database modeling and normalization course. It provides background on a scenario where a consulting firm must design a new personnel database system for a government agency. The assignment tasks students with determining the steps to develop an effective Entity Relationship Model diagram for the system, analyzing risks if steps are missed, selecting and ranking 5 key entities, specifying how to store time-variant data, diagramming a 1:M relationship for employee data, planning the normalization process to third normal form, and diagramming 5 potential entities with dependencies and multivalued attributes. The assignment must be 3-4 pages and follow APA formatting guidelines.

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

2. 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 in Microsoft Word or Visio,
or an open source alternative such as Dia. 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.

3. 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 Excel, Visio, MS Project,
or one of their equivalents such as Open Project, Dia, and
OpenOffice. The completed diagrams / charts must be
imported into the Word document before the paper is
submitted.
Don't use the notes of other students. You might assume
they are a good student, but there really is no way of
knowing how good their notes are. It may be that the notes
contain truncated thoughts or incorporate symbols that only
the writer can understand....
