How does JDataStore provides persistence for mobile/offline computing?

Since JBuilder 2.0, JDataStore provides high performance data caching and compact persistence for DataExpress
�� DataSets, files and Java Objects. The data store has a hierarchical directory structure that allows a single DataStore to
�� persist multiple DataSets, files and objects.

�� The DataStore component can be used with any DataSet that extends from StorageDataSet (TableDataSet,
�� QueryDataSet, ProcedureDataSet). In addition, you can use Java serialization support since JBuilder 2.0. The new
�� DataSetData class can extract edited or unedited rows from a DataSet. DataSetData implements java.io.Serialization so
�� it can be used as a parameter to an RMI method or manually streamed between a client and server as a stream of
�� bytes. DataSetData also has methods for loading its contents back into a StorageDataSet.
