Hi All I would like to know your opinions on advantages and disadvantages of using Messaging Middleware Vs RPC and Distributed Databases in a distributed application?
Thanks
A:
These three are completely different things:
- Message Oriented Middleware (MOM): A subsystem providing (arbitrary) message delivery services between interested systems. Usually providing the ability to change messages' content, route them, log them, guarantee the delivery, etc.
- Remote Procedure Call (RPC): A rather generic term denoting a method of invoking a procedure / method / service residing in a remote process.
- Distributed database: seems quite self-explanatory to me, refer to wikipedia.
Hence it's hard to tell specific (dis)advantages not knowing the actual distributed application better. You could be comparing RPC and MOM. In that case MOM usually is a complete message delivery solution, while RPC is just a technical mean of inter-process communication.

Ok, point taken! But still think I have a point - so lets me explain. Take a train control system which involves connectivity between track, software and other hardware equipemnt. These three technologies could be used for communication between the components or just a Distributed Database(however difficult that might be) But for the sake of argument, the three are possible - if you agree, what are the pros and cons - lets limit MOM to MSMQ in my case.Thanks

MSMQ is a particular message oriented middleware. Like WebSphere MQ is for example.

you're not really answering my question, just telling me what you know about these stuff! I mentioned MSMQ(WebSphere MQ) as I intend to use it for this partucular project of mine.

My point was in disambiguating your question actually. I think you should provide more details on your project to get more help.

Ah ok, this is a model train control system - which includes track, train, signals all send messages to a central Queue or could use RPC for communication? but for the sake of a general argument I wanted to compare Distributed Dbases as opposed to these two technologies.
