First Normal Form

1.To place data into first normal form we remove repeating groups within the primary entities.
2.These repeating groups then become new entities linked together by a one-to-many relationship.

Normalisation
1.The sets or rules to eliminate anomalies and produce a new collection of problem free tables are called normal forms (NF)
2.First Normal Form (1NF) improves the design of your tables.
