For instance, a software company may employ a car dealership to develop a pc system for them. The auto dealer might not have much technical expertise but should certainly appreciate this diagram with just a little of coaching. Consequently, the application developers might not exactly know each of the specifics of running a car dealership. When finalizing the style, it’s vital that you include both technical people and business people to ensure that the application form could have the info that it must function as its intended.
The dealer can study the diagram and offer missing pieces without really understanding database concepts. It’s a lot better to iron out this sort of thing prior to actually creating the database or designing systems around it. That’s just one reason that this type of graphical representation works very well. Other benefits include the cabability to make use of the model to make the ultimate database and also to consult it later as focus on the applying progresses.
