Jeff, a project manager at Top Flight Systems Consulting Co., Inc., has frequently encountered junior systems analysts on his project teams who had great difficulty developing correct data models. Frankly, Jeff was a little tired of always finding glaring errors in his team’s data models, then trying to be patient as the team member struggled to get things right. The time pressure on the consulting engagements always weighed heavily on Jeff’s shoulders.

Since data models seemed to be a particular sticking point for the junior analysts, Jeff decided to develop a set of rules and guidelines for his junior analysts to use in developing data models. Jeff hoped that by providing a concise summary of data modeling tips, he can improve the junior analysts’ performance on this important systems development technique.
