week 5 Assignment – Database Modeling and Normalization

Overview

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.

Instructions

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 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 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 following:
    • • Dependency diagrams.
    • • Multivalued dependencies.

• • The cover page and the reference page are not included in the  required assignment page length. Include charts or diagrams created in  any chart or drawing tool with which you are familiar. The completed  diagrams or charts must be imported into the Word document before the  paper is submitted.

This course requires the use of Strayer Writing Standards. For  assistance and information, please refer to the Strayer Writing  Standards link in the left-hand menu of your course. Check with your  professor for any additional instructions.

The specific course learning outcome associated with this assignment is:

• • Create a database using normalization techniques and logical/physical design best practices.
