JDBC
Schnittstelle über die man von Java auf Datenbanken zugreifen kann (sog. API). Zur Realisierung benötigt man einen JDBC-Treiber auf dem Client und ein Gegenpart auf dem Datenbank-Server.
The JavaSoft JDBC driver categories are as follows:
CLASS 1: JDBC-ODBC Bridge Driver: JDBC-ODBC bridge translates calls into ODBC calls on the client.
CLASS 2: Native API/Partly-Java Driver: Native API translates JDBC calls to their native database API on the client machine using the vendors native database API.
CLASS 3: Net Protocol/All Java Driver: Net Protocol uses all Java drivers deployed on the client to speak to server, which translates call into native API database calls.
CLASS 4: Native Protocol/ALL-Java: Native Protocol speaks directly to database server using the database servers native network protocol.
