Surrogate Key: Surrogate keys are keys that have no "business" meaning and are solely used to identify a record in the table. Such keys are either database generated (example: Identity in SQL Server, Sequence in Oracle, Sequence/Identity in DB2 UDB etc.) or system generated values (like generated via a table in the schema). Natural Key: Keys are natural if the attribute it represents is used for identification independently of the database schema. What this basically means is that the keys are natural if people use them example: Invoice-Numbers, Tax-Ids, SSN etc.

A dichotomous key is used to identify organisms based on a series of choices between two characteristics, leading to a specific classification. A taxonomic key is a type of dichotomous key specifically used to classify organisms based on their taxonomic characteristics, usually down to the species level. In summary, all taxonomic keys are dichotomous keys, but not all dichotomous keys are taxonomic keys.

Normally the difference between a Valet and Master key is the Valet key will not work in the glove box or trunk of the vehicle. The actual differences in the keys are either the grooves in the key or the thickness of the key which restrict it from going into the locks. Occasionally the valet key may not have certain cuts on it to work those locks.
The key difference between the two is in the layout. In particular the type of grass they use and the look and feel.
