The packagejavax.sql
, a standard extension to the Java programming language, provides these features:
Rowsets
- A rowset encapsulates a set of rows from a result set and may maintain an open database connection or be disconnected from the data source. A rowset is a JavaBeans tm component; it can be created at design time and used in conjunction with other JavaBeans components in a visual JavaBeans builder tool to construct an application.
JNDI
tmfor Naming Databases
- The Java tm Naming and Directory Interface tm (JNDI) makes it possible to connect to a database using a logical name instead of having to hard code a particular database and driver.
Connection Pooling
- A connection pool is a cache of open connections that can be used and reused, thus cutting down on the overhead of creating and destroying database connections.
Distributed Transaction Support
- Support for distributed transactions allows a JDBC driver to support the standard two-phase commit protocol used by the Java Transaction API (JTA). This feature facilitates using JDBC functionality in Enterprise JavaBeans components.
