Your organization has just kicked off a major data warehouse implementation project. It is early in the planning stage when you are approached by your supervisor to address some immediate reporting and analysis requirements of the Marketing department. Knowing that the data warehouse implementation is months away from production, you decide to use a data mart to complete the task. Research the two primary approaches to data mart implementation and select the most appropriate option for the situation. Write a 350- to 500-word business-appropriate memo to your supervisor to let her know of your findings. Include a summary of your research and justification and illustrate a high-level conceptual Crow's Foot ERD drawing of your approach.
