Hello Everyone,

I have few questions related to persistent data storage in blackberry, please share ur knowledge i really need it.

1.Firstly i want to know that using which data storage option is more efficient
(a) PersistentStore
(b) FileConnection
(c) RecordStore

2.Then i want to know if i use PersistentStore then how much of maximum memory is available for me to cache my data.

3.Then i want to know that what is the type of file (i.e. its extension) when i create a PersistentObject and where its actually created in Research In Motion, i mean i want to know the location of the file being created.

For ex:- if i create a record store in j2me then its extension is .rms and the recordstore gets created in the appdb folder of particular emulator.


Thanks in advance

Regards
