a jdbc client is software that allows your application to connect to oracle.

jdbc "thin" client is, as the name implies, a smaller version of that software that requires less overhead than other versions.
It's the normal means of connecting from java now.

To quote wiki: JDBC drivers are client-side adapters (installed on the client machine, not on the server) that convert requests from Java programs to a protocol that the DBMS can understand.

These are the simple (and essential) properties of a JDBC driver that will help you understand the concept,

1. Compiled in pure Java and exposed as simple interfaces- hence simple to use as libraries in java code without any understanding of underlying database calls.

2. Driver libraries provided (mostly) by the database vendors and confirms to single java JDBC API guidelines - hence the java code you write for database connectivity does not change for different databases. It is matter of simply changing the driver library to connect to different database vendor.

3.These are called the thin clients as the database client (example: sql*net) does not need to be physically installed on the client machines. The driver libraries create and connect directly via Java sockets internally.

Simple example would be OJDBC14.jar from Oracle and similarly name jar file from MSSQL.
