| I want to know whether implementing web services or message queuing is best for integrating two different application? In short I want to know which one is the better option? It would be of great help if some one can provide me a link or e-book which gives the merits or demerits of these two implementation strategies over each other. |

1. If you have request which can not be lost use MQ messaging.
eg: when request modify source system
2. If you have request which can be lost use Web Services or MQ messaging.
eg: when request get information from source system. If request fail you can send another one.
Everything depends on lots of things. It't trivial, but it is true.

Hi Marcin,
If the system we are integrating have the requirement of both synchronous and asynchronous messaging, what would be the better option? You said "Everything depends on lots of things", can you tell me some other points I mean issues related to performance or the best practice. |

asynchronous messaging certainly requires a queue based system.. synchronous calls can be implemented by both queue based systems (request/reply model) or usng web services.
As mentioned earlier in the post, assured message delivery mandates the use of a queue based system .
Interaction b/w independant systems across firewalls/enterprises is much more easily accomplished using SOAP over HTTP.
Queue based systems offer a more robust and scalable framework also in my opinion.
So all in all it depends on what kind of systems you are looking at integrating and their existing interfaces if any and the criticality of processes and the level of transactionality required for the operations..
Hope it helps
