xml - What format do sites like Facebook use to store data for personal profiles? -


i started dealing large sets of data stored in xml files. i've wondered how facebook , other networking sites store information associated individual profiles (name, profile picture, wall posts, etc.) , feel xml not best way store information. i've tried finding information google haven't been having luck.
