The Database Management

The model will contain the attributes detail for each entity.
The term of this database design can be described as many parts of the design from the database system or you can also defined it as the logical design from the structure of the base data that used to keep the data. The relational model we can see the view and the tables while in the object database you can see that the relationship and the entities map to named relationship and the object classes directly. But the term of this database design can be used to describe the whole process from designing the base data, forms, and also the queries as the part from the whole application of the database.
