Types of RowSet:
Connected RowSet:
A connected RowSet object uses JDBC driver to make a connection to the database and maintain that connection through out its life span. JdbcRowSet is a connected rowset.
Disconnected RowSet:
A disconnected RowSet makes a connection to the data source only to read in data from a ResultSet object or to write data back to the data source. After reading or writing data it is disconnected. A disconnected RowSet has no connection to its data source and operates independently.
