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 its database, and why? How does each organization access its database to perform analysis? Have the managers and their staff received training in any query or reporting tools? What do they like about their databases, and what could be improved? Weighing the information obtained, identify which company has implemented the best customer database.
