Thanks guys I will investigate those features.

Re: [sqlite] Running in memory only
Salut Benjamin, Simplest way to make that happen is to use a ram disk, google for 'RamDisk' and the platform you are using. Then you can use the existing sqlite binary/library but all I/O occurs in memory. When you want to persist, you just copy it to a hard disk... D.
