Technology for fast accessing the Databases.

Hi All,

Can you please let me know what would be the technology for fast accessing the server database from the client. If I have database of lacs of rows, and I want to access it withhin a fraction of second then what would be preferrable.

What technology the gmail is using so we could connect to it within a fraction of second after entering the appropriate username and password.

Thanks and Regards

-Ibrahim
