Computers do not understand how people or products are different
Normalization
So, we need to identify everything for the computer (ID)
The way we identify something is with Keys
Primary Key
Unique identifier of an entity (never same)
Secondary Key (Index)
Helps search through DB quicker (can be the same)
Compound Key
Sometimes you can create an identifier by combining two fields
e.g. order nr + product nr
Foreign Key
Primary key from other table (other entity)
