Default Offline Application in Black Berry

Please Login to Remove!

Hi,

I have a question -

"How off-line application is supported by Black Berry ?"

I read some documents and came to know they generally talks about "Always on, Always Connected".

Which is the best approach to develop wireless application ?

Online , Off-line or online/off-line both (mixed) ?

Regards ,

Amit

Hi ,

Thanks for your quick reply..

What about performance , if application is online and on each request its trying to get data from main server application ?

What if there is lot of data to be used in application ?

How important role BES can play in integrating mobile application to some back end application ?


Regards,

Amit

Performance depends on you re coding efficiency, on network ...
One concern you must have is power. If you re application is processing/sending/reading lot of data the power will go down (very) quickly.
Using Bes is interesting for security purpose as data are crypted between the bb and the BES. While not using the Bes provide a clear connection.
