Best Online Database

I have stumbled at www.365chess.com and found it interesting. I was aware of Chessbase.de but sometimes it doesn´t seem to work properly. I mean you drag and drop pieces util a specific position and then press the search button and it retrieves nothing......I use databases heavily because I face online chess as an excellent opportunity to study.

Is it free?

I think it only requires free registration.

Ok, thanks! Gonna check it later. It's blocked by the firm's firewall...

It only took 8 and half years for someone to comment on this lol. The chessbase app works great for me. It's not free though.

 Or people can just use the one here. It may not be updated as quickly but it works.
