So when we create a record, which is an insertion,…or when we delete one or update one,…we don't damage the rest of the database…so that it's not really a reflective…of the information we want.…There are different degrees of normalization.…So why not one huge table?…Well, when relational databases were first put forward,…the largest cost factor of the big three,…which is processing power, memory, and storage,…was storage.…
