1.1.1 What is JDBC

1.1.2 What is database Driver

  • Driver: A bridge for communication between two devices (applications).

1.1.3 Why learn JDBC

  • In the absence of JDBC, Java programmers need to know the MySQL driver API if they want to develop a system that uses Java to connect to the MySQL database, and Oracle database driver API if they use Java to connect to the Oracle database.
  • SUN provides a uniform set of specifications (interfaces). The various database manufacturers then provide implementations of this interface. This set of interface specifications is the JDBC specification.
