E Correct answer
Explanation

Data mart design must begin with understanding the business requirements of the department that will use it. This determines what data to include, how to structure it, what metrics to calculate, and how to present the information. Database backups, query performance, data entry processes, and table counts are implementation or operational details that come after defining requirements.
