Need a maintainable Table with Large Field for URL String

Hi, I need to have a table where I can maintain a Web URL of an unspecified length. I have some URLs longer than 500 char. Is it possible to create a maintainable Data Dictionary Table with a couple of fields for a key and 1 last field that is of type string? I would need to be able to maintain this table manually and be able to access the contents via ABAP...

Is this possible? If not is there another possiblity?

Thanks!
