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 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.
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.Use this template APA_Template_With_Advice_(6th_Ed) .doc sample doc Assignment 4.docx
