The primary key is the field in a table that uniquely identifies each record. It is also used to establish relationships between tables when creating a database. A secondary key is an additional field or combination of fields used for indexing and sorting data, while a composite key is a combination of two or more fields that uniquely identifies each record in a table. "Main key" is not a commonly used term in database design.
