JDBC (Java Database Connectivity) is an API for connecting programs written in Java to databases.
Using JDBC, a query or statement is passed to the database in the SQL language. Data is returned by the JDBC Driver, and is then available for use by the Java program.
Each type of database requires a separate JDBC Driver, which is provided as a JAR file, and installed into the WEB-INF/lib folder of the application.
Drivers are available for all popular databases, either free, or commercially.
