As a team of three or four classmates, interview managers from three different organizations that have implemented a customer database.
• What data entities and data attributes are contained in each database?
• What database management system did each company select to implement their database and why?
• How do they access the database to perform analysis?
• Have they received training in any query or reporting tools?
• What do they like about their databases, and what could be improved?
• Do any of them use data-mining or OLAP techniques?
Weighing the information obtained, identify which company has implemented the best customer database.
