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 around and tended to result in the blame-game. You’ve bought every pill and tonic you could find (ESBs, network appliances, UDDI registries, load balancers, etc.), each with varying degrees of success.... (more)

Identify & Achieve ROI with Your SOA Training

For many people, even entire organizations, the approach to education seems to be along the lines of learning facts, figures, details, tools and standards.

It may not fit on your lot or connect smoothly to your utilities, requiring ... (more)

Which Came First, the SOA or the Data Model?

Recently I have been engaged in two Master Data Management (MDM) initiatives within the context of a larger Service Oriented Architecture (SOA) adoption plan. In both cases, the client found themselves at an impasse regarding how to resolve conflicts between the master data model and the data model required for one or more SOA artifacts (i.e. business process, service interface, etc.).

Wireless Web Serviceswith J2ME Part IISOAP or XML-RPC? The answer depends on your needs

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... (more)
