What is the difference b/w natural key and surrogate key
Answer / babulcity
Natural Key is key attribute column of an entity with
distinct values i.e without duplicates/NULL.
Eg: For natural Key we can define constraint like PK,FK
Surrogate Key is an substitute key which is not a part of
attribute of entity & is unique but it can be used to act as
PK,FK when you cannot use the Natural key.
