[offtopic] How do you name a table...

Hi,

How do you name a table which sole purpose is to store a list of values?
E.g.

Table: sex
id name
-------
1 male
2 female

Table: day
id name
-------
1 Sunday
2 Monday
3 Tuesday
4 Wednesday
5 Thursday
6 Friday
7 Saturday

Is this:
a. Lookup table
b. Classifier
c. Cypher(er)?

I'm looking for the appropriate term in English.

Regards,
Ognjen
