Describe the steps that you would use in order to convert database tables to the First Normal Form, the Second Normal Form, and the Third Normal Form.​

1. First normal form:

The first step in normalisation is putting all repeated fields in separate files and assigning appropriate keys to them.

2. Second normal form:

In this stage of normalisation, all non-key elements that are fully specified by something other than the com­plete key are placed in a separate table. Normally, these non-key elements are dependent on only a part of a compound key.

3. Third normal form:

This stage of normalisation enables elimi­nating redundant data elements and tables that are subsets of other tables. The redundant elements are those non-key data elements that are placed in more than one table of the virtual data elements.
