Java Database Connectivity (JDBC)

RowSet interface, part of the javax.sql package, introduced in J2SE version 1.4, provides a lightweight means of passing data between components.

At this release, as an aid to developers, the RowSet interface has been implemented (as JSR 114) in five of the more common ways a RowSet object can be used. These implementations provide a standard that developers are free to use as is or to extend. Following are the five standard implementations:

• JdbcRowSet - used to encapsulate a result set or a driver that is implemented to use JDBC technology

• CachedRowSet - disconnects from its data source and operates independently except when it is getting data from the data source or writing modified data back to the data source. This makes it a lightweight container for as much data as it can store in memory.

• FilteredRowSet - extends CachedRowSet and is used to get a subset of data

• JoinRowSet - extends CachedRowSet and is used to get an SQL JOIN of data from multiple RowSet objects

• WebRowSet - extends CachedRowSet and is used for XML data. It describes tabular components in XML using a standardized XML schema.
