Suppose i have a table with 3 fields
Person_id, Name and address. Now the problem is that a person can have multiple addresses. and the principle of atomic values says that data should be atomic.
So then how am i suppose to store multiple addresses for a single person ?
You’re supposed to create an
ADDRESStable that has a foreign key linking it to aPERSONrecord, i.e.PERSON_ID. This is the “relational” component of a relational database, and it’s why it’s more flexible than a flat file (which is like a single table).
