Java and Database Connectivity: Slide 66

Java and Database Connectivity

The Driver

A class in a package which you load into your Java system which knows how to talk to your particular database
Four types
1. JDBC-ODBC Bridge Driver talks to an ODBC connection using largely non-Java code.
2. Native API, Partly Java uses foreign functions to talk to a non-Java API; the non-Java component talks to the database any way it likes
3. Net Protocol, pure Java talks to a middleware layer over a network connection using the middleware's own protocol
4. Native Protocol, pure Java talks directly to the RDBMS over a network connection using an RDBMS-specific protocol
