JDBC is a core API of Java 1.1 and later. It provides a standard set of interfaces to SQL-compliant databases.

PostgreSQL provides a type 4 JDBC driver. Type 4 indicates that the driver is written in Pure Java, and communicates in the database system's own network protocol. Because of this, the driver is platform independent; once compiled, the driver can be used on any system.
