1. The input to the data normalization process is a list of the attributes in the database and a list of the functional dependencies among them.
2. The data normalization process is known as a "composition process."
3. A group of tables is said to be in a particular normal form if every table in the group is in that normal form.
4. In first normal form tables every attribute value is atomic, that is no attribute is multi- valued
5. Converting from first to second normal form involves subdividing tables to remove transitive dependencies.
6. A transitive dependency occurs when a non-key attribute determines another non-key attribute.
7. The data normalization process is progressive. If a group of tables is in second normal form it is also in third normal form.
