Sample text

Within this model, we could capture this information by creating another Group object for Taylor and Long (Boys High Early Leavers, say) with a different set of dates. That would cope with knowing who is coming and going when. If it is essential, however, that the system needs to record that these two groups of Boys High people are somehow “together,” the data would need to be modeled differently. The data model also tells us that a guest must belong to a group. What else does this tell us about the definition of a group?

A data model is a precise description of the data stored for a real–world problem, in much the same way that a mathematical equation describes a real-world physical event, or an architectural drawing describes the plan of a building. However, like a mathematical equation or an architectural plan, the data model is neither a complete nor an exact description of a real situation. It will always be based on definitions and assumptions, and it has a finite scope. For example, a high school student’s simple mathematical equation to describe the path of a ball tossed into the air will probably make assumptions about the constancy of the gravitational force and the absence of air resistance, and will likely assume low speeds where relativistic effects can be ignored.

Let’s assume we discover that the drivers are assigned to be on duty for various time units. Obviously, being able to maintain and print out duty rosters would be useful. However, automating rosters doesn’t directly contribute to our main objective. It is agreed to leave the rosters outside the scope of the system for now. The receptionist will use information available independently of the database (probably a list of names pinned to a notice board) to determine who should be assigned to deliver an order.
