First Normal Form (1NF) is used to describe a database where all data is atomic and isomorphic. This means that each field has exactly one value (it is not a combination of values), and that does not depend on any other value in that row, and each row does not depend on any other row in the same table (although they may depend on other tables; that's the point of foreign keys).

How many normal forms are there?
In database design, there are several normal forms, typically including the first three: First Normal Form (1NF), Second Normal Form (2NF), and Third Normal Form (3NF). Beyond these, there are also Boyce-Codd Normal Form (BCNF), Fourth Normal Form (4NF), and Fifth Normal Form (5NF). Each normal form addresses specific types of redundancy and dependency issues to ensure data integrity and efficiency in relational databases. Higher normal forms exist, but the first five are the most commonly referenced.

Is a database that is in third normal form automatically in first and second normal form?
Yes, each normal form builds upon the lower forms, such that a database in form N will also be in form N-1, N-2, etc. A database in fifth normal form, for example, will also be in first through fourth normal forms.
