Device Support for Persistent Storage
Each MIDP-compliant device maintains a dedicated area of device memory for persistent application data storage. MIDlet data stored here persists across multiple invocations of the applications that use it. Both the physical location and the size of the data store are device dependent.
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.
