Modeling and Mapping

bQuestion 1

Design a database schema for the proposed Database Design Proposal in Module 1.
Identify and list all relevant entities and their relationships:
1) Select no less than five entities.
2) Provide a diagram.
3) Map this to a database schema.
4) Provide a data dictionary for all entity attributes.
Focus on one or two areas of your design that seemed especially difficult to develop and provide a brief assessment of the difficulty you encountered in modeling or mapping to the schema. In addition, provide the rationale for the design chosen, its limitations, and its possible extensions.
Tip: If you do not have access to ER modeling software or a diagramming tool like Visio or OmniGraffle, you can simply create diagrams in a presentation tool like PowerPoint. This is an essential skill which is used in the field.
APA format is not required, but solid academic writing is expected.
Instructors will be using the rubric to grade the assignment; therefore, students should review the rubric prior to beginning the assignment to become familiar with the assignment criteria and expectations for successful completion of the assignment.
This assignment will be utilized again in Modules 4 and 5. Prior to Module 4, review any feedback provided to you by the instructor.

Question 2

You are the database administrator for your company. Since the organization has now merged with another company, you are asked to explore the possibility of upgrading to a data warehouse. Describe what information you will need to gather in order to make a decision. Decide how you will respond to your CIO and address questions such as the types of platforms that are available and the implications for implementation. 

In response to your peers, discuss the potential roadblocks that could delay the implementation of the proposed plan.
