Data source Design

There are several types of database design, including relational, multi-table, and object-oriented databases.

This is because improve your performance the type of info can change the moment other information is certainly added or deleted. Should you have a list of brands and includes, this does not show that the same person lives at different the address. But if you could have a list of the address, this is important, because it will be difficult to find the resolve of a person living at that house.
