Explain briefly each of the first three levels of normalization

What will be an ideal response?

The first level of normalization removes all repeating groups and arrays from entities, and makes sure that every column contains a single value all of the same type. Second Normal Form removes functional dependencies, which are subgroups or sub themes of attributes within an entity. Each subgroup should be made into a separate entity. The third level of normalization removes transient dependencies from entities. This ensures that all attributes describe the primary key of an entity and not some other attribute.
