One of the cornerstones of good table design is the process of normalization. Normalization proceeds through different stages. The result of each stage is called a "Normal form." So if we have completed the first stage we say the database is in "First Normal Form", and after we have completed the second stage we say the database is in "Second Normal Form" and so on.
