SQL integration for offline database

Hello,

I am trying to integrate datable editor into tablet/ipad apps. I am now looking for table/form entry like this product.

I need it to use a sql database that is offline. It will be on the local device.

Then when the user is in wifi range, I will sync/upload the changed data to the office server. I have this already.

Has anyone done this and maybe some example to look at and test would be great. I just want to make sure before I purchase this product.

Thanks

Howard
