Обсуждение: [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

I'd call it a lookup-table.

lookup (*_lu, lu_*) or enum or just what it is (gender,
document_type, ...)

I try to make it an ENUM when it's very unlikely to change, i.e. day of
the week is a good candidate for an enum ... when's the last time that
changed?

For lookup tables that aren't static enough to be an enum, it usually
ends up appended with _list (i.e. gender_list, county_list, etc)

As  others have said enum for things that are static like day, week,
month etc..
For things that are not static and change like system/application
settings  i do something like this

CREATE TABLE syssettings
(
   sys_id serial primary key,
   sys_group text,
   sys_value text,
   sys_displayvalue text,
   sys_datatype text DEFAULT 'text'
)

This allows for easy grouping values together and assigning the data
type for casting, along with how the information is to be displayed in
the user interface.

example what the data looks like:  the below data is used to create
<option> pull down list on a website.  So if the user of the application
wants to add more options all they have is make an entry.

15;"ExamLevel";"1";"Level 1";"integer"
16;"ExamLevel";"2";"Level 2";"integer"
17;"ExamLevel";"3";"Level 3";"integer"
18;"QuestionOrder";"StandardList";"Standard not random";"text"
19;"QuestionOrder";"RandomList";"Random from List";"text"
20;"QuestionOrder";"Random";"Random From All Questions";"text"
21;"ExamType";"MPI";"MPI";"char(10)"
22;"ExamType";"RT";"RT";"char(10)"
23;"ExamType";"UT";"UT";"char(10)"
24;"ExamType";"ECT";"ECT";"char(10)"
25;"ExamType";"LPI";"LPI";"char(10)"
