DATA Base to big for hosting

Hello,

My website http://www.consoledomination.com and http://www.retrodomination.com both have a issue where the database is getting to big fast.

Console Domination has around 300 articles loaded on the site and it’s database is 511 meg!

Retro Domination is far less with a total of around 100 articles and it;s database is getting close to 230meg.

Please help, am I doing something wrong?
