Record Management System (RMS)

RMS: This Java tip explains RMS Record Management System for storing persistent data. A record store consists of a collection of records which will remain persistent. The RMS API abstracts the device-dependent details of the storage area and access to those details, and it provides a uniform mechanism to create, destroy, and modify data. This ensures portability of MIDlets to different devices.
