JDBC Development Process

Java Database Connectivity (JDBC) is a Java API for executing SQL statements. It provides a unified access interface for multiple relational databases, enabling applications to work with data based on it. GaussDB(DWS) supports JDBC 4.0 and requires JDK 1.6 or later for code compiling. It does not support JDBC-ODBC Bridge. The following figure shows the JDBC application development process.
