Load custom settings from database in all pages

[eluser]Unknown[/eluser]
I'm trying to figure out how to do this but I'm not sure..

I want to save custom settings in the database which have to load on each page.

Current database structure:

Code:

Settings
-> id
-> name
-> value

For example:

Code:

Settings
-> 1
-> site_name
-> My swiss white shepherd dog

How can I load all the entries from this table into memory so that it can be accessed on every page?
Is it possible with a hook? And which code can I use to make the array (I think it has to be in an array?) accessible from every page?

Thank you in advance.
