Hi I replied to the 2 questions in your other emails :)
Cheers Nic > 1. Hosting database server in iOS > > I've developed a Point of Sales (POS) app on the iPad and iPhone. The app > builds with local SQLite database. The app mainly operates in a single store > (close loop) environment with local network router.

I want one iPad at the cashier counter to host the database and > the rest of other iPad devices connecting to the host.

Web Services Performance > > Again, I've developed the Point of Sales (POS) application in Windows and > iPad (iOS devices) app using local database such as MSSQL Server Express and > Sqlite3.
