Java Database Connectivity (JDBC) is a Java application programming interface (API) that allows SQL statements to perform database operations. The JDBC API consists of classes and interfaces written in Java. The JDBC API allows developers to write portable database applications using pure Java. These applications are portable because database-specific JDBC drivers convert the JDBC API call to a database-specific call.
