Last month in Part I (WSJ Vol. 2 Issue 1) we discussed J2ME and accessing Web services from wireless devices using the XML-RPC protocol. In this article, we will consider SOAP as a vehicle for accessing Web services from wireless devices, comparing and contrast-ing it with XML-RPC. Our sample application will again be a J2ME midlet, however, we will use EnhydraME's kSOAP rather than kXML-RPC to provide the protocol's implementation. Overview of SOAP The Simple Object Access Protocol is, according to the 1.1 specification, "a lightweight protocol for exchange of information in a decentralized, distributed environment." The protocol is entirely based on XML, vendor-neutral, and one of the cornerstone technologies in the Web services revolution. It is quite similar to XML-RPC, but we will examine that more closely in the next section. SOAP was originally conceived and ... (more)

Which Came First, the SOA or the Data Model? - Part 2

In a previous post I blogged about the strong synergy between SOA and MDM. More recently, I explored the subject of service oriented data modeling (part 1 of this post) and how to resolve the inevitable conflicts that arise between your SOA view of data and your enterprise or MDM view of data. In this second article, we explore a second scenario (see below). Scenario 2: Client B has an existing SOA implementation and has recognized that the underlying physical data is disparate and incongruous. They decide to move forward with an MDM initiative to clean-up the design, management, ... (more)

Real Value in Cloud Computing

I have officially come full circle from my position last summer regarding the reality of Cloud Clomputing in which I presented a skeptical view of Cloud's potential to actually materialize.  It is now quite apparent to me and increasingly to my clients and readers, that Cloud is real and it is here to stay.  I was reminded of this reality just this morning.  As I read through various news stories online, I came across the following fascinating story from Fortune Small Business - Cloud Computing: Supercomputers for Hire. The article clearly articulates a real life value proposition... (more)

The Hype About .NET

You've heard the hype about .NET. You've read a couple of vague articles about dynamic discovery and invocation, service-oriented architecture, and how SOAP and a handful of other XML standards are forever changing the software industry. These ideas have intrigued you and you're interested in learning more - or at the very least, you recognize the importance of being able to add these acronyms to your resumé. In either case, you want to explore the world of .NET, but are unable or unwilling to fork over a thousand bucks for Microsoft's Visual Studio .NET product. This article is ... (more)

Ten Steps to Successful Cloud Adoption

A Journey of False Starts This is not the first time you’ve had your heart set on revolutionizing your information systems: One year, you rolled out a big Enterprise Application Integration (EAI) initiative, but it was too brittle and carried high maintenance costs. For a while you experimented with Web Services, but found that while they were easy to work with, they were largely insufficient to meet your broader needs due to a lack of architectural design guidelines. Out-sourcing, in-sourcing, up-sourcing, down-sourcing, and cross-sourcing just seemed to shuffle the work aroun... (more)
