How do you structure config data in a database?

Question

What is people\'s prefered method of storing application configuration data in a database. From having done this in the past myself, I\'ve utilised two ways of doing it.

Answer 1

I can think of at least two more ways:

(a) Create a table with key, string-value, date-value, int-value, real-value columns. Leave unused types NULL.

(b) Use a serialization format like XML, YAML or JSON and store it all in a blob.
