What is a Loosely Coupled System?

In a loosely coupled system (e.g. Service Oriented Architecture i.e. SOA), the dependencies can be either a Real Dependency or an Artificial Dependency.

Real dependencies are the services that you need to fulfil your need, this is something that cannot be eliminated or reduced.

Artificial dependency on the other hand are the features you need to adhere to in order to consume the services you need. Typically these fall in the categories of platform dependencies, API dependencies, language, etc. Although artificial dependencies cannot be eliminated it can be reduced.

A loosely coupled application is on that minimise its Artificial Dependency.

This blog is my personal blog and while it does reflect my experiences in my professional life, this is just my thoughts. Most of the entries are technical though sometimes they can vary from the wacky to even political – however that is quite rare. Quite often, I have been asked what’s up with the “gibberish” and the funny title of the blog? Some people even going the extra step to say that, this is a virus that infected their system (ahem) well. [:D] It actually is quite simple, and if you have still not figured out then check out this link – whats in a name?
