Java Database Connectivity (JDBC) is an application programming interface (API) for the programming language Java, which defines how a client may access a database.
SUMMARY
Sun Microsystems released JDBC as part of Java Development Kit (JDK) 1.1 on February 19, 1997. Since then it has been part of the Java Platform, Standard Edition (Java SE; now from Oracle Corporation).
A set of rows obtained by executing a SQL SELECT statement in a database is known as a result set (ResultSet interface). The ResultSet can be updatable. The RowSet interface inherits from the ResultSet interface.
A ResultSet is not Serializable. A RowSet is Serializable, it can be sent over the network or saved to a disk for later use. A ResultSet is always connected to a data source. A RowSet object does not need to be connected to its data source all the time. It can connect to the database when needed such as to retrieve/update data in the data source. The two properties of a RowSet, serialization and connectionlessness, makes it very useful in a thin client environment such as a mobile device or a web application
