There are surely lots of issues that the person must address if he is going to take the data modeling tutorial. If he can take care of these various issues, then he should be able to master this activity in no time. If he wants to find success in this activity, then it is highly recommended that he follows these easy steps.
He should first think about the name that he will be giving to the entities that he will be making use of. There should be clarity and then cohesion in the name that he is going to assign. If he chooses a name for the entities, the best thing for him to do is to ensure that the name properly represents the entity. Also, think about which language to use.
When thinking of the design, always think about the audience. He is making the model for them, thus he needs to follow a certain rule of thumb when it comes to giving the entity names. It should be universally recognizable. Anyone who reads it should be able to understand what it means. Basically, do not use abbreviations and acronyms.
There is a dictionary that will be created for the entities. In the dictionary, he will be writing all sorts of note-like things. For this one, he should make sure to take note of those identified entities that he had no time to analyze. Moreover, he should then come back to that entity as soon as he can. Always aim to identify all the possible relationships with the entities.
There is a need for the person to mark the occurrence of each identified entity. This is made easier if he makes use of the sub-type to mark this occurrence. If he does this, he should also keep in mind that he has to make sure that the occurrence of the said entity should be limited to one time only in that sub-type.
Make sure that he does not make use of any weak relationships, whatever the cost. This will only make his entire model inappropriate. If he makes a mistake here, he will have to start over from scratch. If he really insists, then he should know that only gerunds are allowed. Moreover, the gerund can only be used if it is already the last resort.
Another important thing that he will have to be clear with is the drawing. It should be properly organized so that it can attract the attention of the readers visually. This means to say that he will have to pay attention to the weight of the diagram. Moreover, he has to use the white spaces properly along. Position the elements properly too.
Think about the overall model. It is crucial that he knows how to break them off into different topics. If he does this, the diagram that he has drawn will only be concerned with at most two subjects this is a good way to allow the drawings to represent the entire logical horizon.
The most important tip for the data modeling tutorial lies in the lay out of the model. If the model is for a publication, then it is highly recommended to lay it out in portrait. On the other hand, lay it out on landscape if it is only for the screen since it is more efficient this way.
