I am developing one application in J2me MIDP 1.0
It requires local database management. I have heard about recordStore but can we use it for permanent storage?
Yes, your application can store data using a RecordStore, and you can get it back later even if the application or the phone has been shut down.
EDIT:
One example I found: http://www.roseindia.net/j2me/read-write-midlet.shtml
