Difference between loosely coupled and tightly coupled.
What is difference between Loosely coupled and tightly coupled application.This is in context of JMS(Java Message Service)like example.:-
"Messaging enables distributed communication that is loosely coupled and messaging differs from tightly coupled technologies such as Remote Method Invocation "
What exactly above quotes mean.

Hi Prasana,
Is this is the case will be true in JMS also.
If yes then i can accept your answer.

tightly coupled
Refers to two or more computers linked together and dependent on each other. One computer may control the other, or both computers may monitor each other. For example, a database machine is tightly coupled to the main processor. Two computers tied together for multiprocessing are tightly coupled. Contrast with loosely coupled, such as personal computers in a LAN.
In terms of application software, the meaning is similar - an app or component which is tightly coupled depends on another app or component and if the other app has changed it will not function properly. Tight coupling is a Bad Thing. Loose coupling is desirable, it enables an app to change the way it works internally without affecting other components which use it.
JMS is loosely coupled because it allows disparate systems to subscribe to a queue or topic unlike RMI which directly uses the objects that it needs.
Cheers,
Jonathan
