Foil 8 Driver class creates Connection

From Overview of JDBC and its use with Microsoft Access UC Web Applications Certificate -- June 26 97. by Nancy McCracken(Sangetta Aggarwal, Udayan Parvate, Tom Pulikal)
1 The user requests the DriverManager class to make a connection to a particular database with user and password. The DriverManager then asks each available driver if it can handle that request until one can; the driver then makes the connection. String url = "jdbc:odbc:fred"; Connection conn = DriverManager.getConnection (url, "userid", "password");
2 The form of the url is &#060protocol&#062:&#060subprotocol&#062:&#060subname&#062
  • the protocol is always jdbc
  • the subprotocol is a keyword registered by the driver authors, odbc is a standard one
  • the subname format is very flexible and is designed by the driver author - just follow their examples!
