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 designing, it is very important for him to design the database according to the audience. This means to say that he will have to think about having the names universally recognizable. It is important that anyone could easily understand what the names meant. With this in mind, he should then stay away from acronyms and abbreviations.
Be sure to know how to make use of the dictionary in the program. There are dictionaries available for the person's use which gathers information about the entities used in the program. Even those entities that are yet to be analyzed are written there. He should aim to clear out these kinds of entities as quickly as he can.
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.
Be sure to avoid those weak relationship names. Basically, he does not really need to use those statements such as related to. The relationship between the entities should already point this one out clearly. For the gerund, it can be employed but only as a last resort. He should still aim for concreteness with the names.
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.
It is important for the data modeling tutorial to think of the lay out for the model. Portrait is the best to use when it is for publication. For the screen, the most efficient would be the landscape form.
