I thinking in use a table to record software configuration (like
*.ini files). But I wish to know... what is the best Create a Table
with many columns or a table with two columns and many records?

Example

CREATE TABLE CONFIG (
"SPLASH_SCREEN" BOOL,
"DEFAULT_USER_NAME" BOOL,
"ANOTHER_CONFIG_TAG" BOOL,
"YET_ANOTHER_CONFIG_TAG" BOOL
.........
"many_CONFIG_TAGs_later" BOOL)

OR

CREATE TABLE CONFIG (
"CONFIG_TAG_DESCRIPTION" VARCHAR(..)
"CONFIG_TAG_VALUE" BOOL)

I think that example 1 is more fast for a select, but example two
are much more easy for mainteanence (that´s the word? sorry the english..)
there´s a best choice in this case?

many thanks
