JDBC TYPE 3 driver -more explanation?

[Manish Shinde]

what i understood by reading in different post/books about JDBC Type 3 driver (Net pure Java) is that In a Type 3 driver, a three-tier approach is used to accessing databases. The JDBC clients use standard network sockets to communicate with an middleware application server. The socket information is then translated by the middleware application server into the call format required by the DBMS, and forwarded to the database server.

but this answer didn't satisfy me.
Can anybody explain working of the JDBC Type 3 driver (Net pure Java) little bit in detail ?
