Questions tagged [rms]

In Java ME MIDP, RMS stands for Record Management System API, a persistent storage mechanism, through which MIDlets can persistently store data and retrieve it later. It is also a popular R package where it is an acronym for "Regression Modeling Strategies".

The javax.microedition.rms.RecordStore class encapculates an RMS record store. It provides several methods to manage as well as insert, update, and delete records in a record store. Each record store has Record Header and a collection of Records.

Record Header contains the data (meta-data) about of the Record Store. The various header information stored in a Record Header is.

  • Reference to the first record in the Record Store.
  • Version Number of the Record Store. This parameter is zero for a newly created data store and is incremented by one for each modification to database.
  • Number of records in the Record Store.
  • Last Modified Time of the record store is updated to the header. This information can be used for coding custom synchronization algorithms as RMS by itself does not do any data synchronization.
  • Next available Record ID in the Record Store.
  • Reference to next available Record location. This reference is used by the RMS to insert a new record.
