Service Oriented Programming

Service Oriented Programming brings the SOA approach to individual applications. It naturally enables SOA in the organisation but it can be started with a much smaller scope. Even if your organisation has not adopted SOA you can still do SOP in your own project or within your section.

The beauty about SOP is that it transcends technologies or particular environments. You can write a JAVA/JavaScript web app on top of JSON services, a .Net SmartClient consuming WCF services, a Silverlight app that uses .Net Remoting to get data back from the server or a GWT app with RPC calls.

The idea is always the same. The application consists of a series of services that expose some functionality in an independent manner. You build the UI by consuming those services to get the required data and create the UI components. The UI is always built on the client; there is no UI related code in the back-end. As a result you can write different front-ends for your application without changing the services.

It is interesting to see how the same development paradigm is appearing in all these different environments. If this is the way forward we are leaving behind server-side UI frameworks like ASP .Net or JSF. Try as they may to add AJAX support these frameworks are based on a fundamentally different approach to building (in this case) web applications. Only the general fear traditional developers have of Javascript might save them.


New gig

It’s been an interesting couple of months looking for a new job. Very slow at the beginning but things started to move faster around October. Finally having Australian citizenship also helped.

I left Haley to go back contracting. They’ve now announced that they were bought by Oracle. It’ll be interesting to see what happens with Haley’s products. Oracle interest seems to be solely on the Determinations Engine. In any case I wish everyone at Haley all the best in this new phase.

I will be starting at the Department of Education, Employment and Workplace Relations (DEEWR) on Wednesday.  Education and Employment were two separate entities that have now been merged (again). I had a couple of gigs before on the Employment side.

From what I heard on the interview I’ll be working with WCF and NHibernate. I’m excited about going back to enterprise .Net development after 2 years away from this space. Microsoft has released so much stuff in this time that pretty much everything is new to me now. I’m looking forward to that. Also I finally get to work with an ORM like NHibernate.
