connect to remote database from mobile app

[inageib]

Hi,
I want to develop a mobile app (Android and iOS) using Delphi XE 8, I will need to get and change data in the remote server over the internet, does DevArt provide a component or SDK for that ?

The database is Firebird.

You can develop mobile applications using IBDAC to organize access to InterBase. InterBase supports mobile operating systems starting from InterBase XE3. To test IBDAC functioning on mobile platforms, you can use our Mobile demo project. It can be found in the 'Demos\Mobile' folder relatively to the IBDAC demos installation path.
You cannot connect to a Firebird server from Android using IBDAC, because Firebird does not officially support mobile operating systems. We will add support for Firebird under mobile operating systems as soon as Firebird supports mobile operating systems.
Pay attention, Mobile Development is available only in Professional and Trial Editions of IBDAC.

If I connect directly to InterBase over the internet is it going to be fast ? does IBDac support support offline mode when there is no internet connection ?

Connection speed to the server in the Internet depends on many external factors and may vary. You can test access speed to the needed server on our mobile demo project. The link to the project was provided above.
IBDAC has no support for work without connection to the server, but it has options for work in unstable networks. The article http://www.devart.com/ibdac/docs/#unstable_network.htm describes ways of IBDAC optimization in order to work with unstable network connection.

Is there any demo or tutorial for using IBDac with Datasnap ?
