You might have seen the recent news reports about the collision between U.S. and Russian communication satellites. The U.S. satellite was one of the Iridium satellites. What wasn’t reported and you probably don’t know is that an object database management system (ODBMS) is an important part of the Iridium system. Even though ODBMSs are a [...]

The typical definition of an atomic task or process is one that cannot be decomposed further. This is vague and subject to interpretation. The Decomposition Matrix on this site uses a specific definition: A task (for business process diagrams) or a process (for data flow diagrams) is atomic if every input relates to every output [...]

My last posting referenced the criteria for a well-formed business process diagram mentioned in Business Process Driven SOA using BPMN and BPEL by Matjaz B. Juric and Kapil Pant.

I recently received two new books on business process modeling. Both books looked interesting because they had great titles. As it turns out, one book is great and the other not so good. The not so good book is Business Process Driven SOA using BPMN and BPEL by Matjaz B. Juric and Kapil Pant. There [...]

You should consider an application server when you have a need for:
Integration with existing systems and databases
Website support
Secondary reasons to use application servers derive from the primary reasons.
A few secondary reasons are:
E-Commerce
Web-integrated collaboration
Component re-use
One way to look at application servers is that they are a formalization of a
solution to a problem that has been around for a long time. That problem can
characterized as a need to create an integrated presentation and processing
environment for existing systems and databases. The presentation has pretty much
been decided with browsers now being the dominant interface. This is why you usually
see a Web server paired with or included in an application server. The integrated
processing has been moving towards components for some time. Application servers
provide containers for such components along with application program interfaces
(APIs) to support the components. These APIs are to the existing systems and
databases.

JBoss in Action: Configuring the JBoss Application Server by Javid Jamae, Peter Johnson Average Customer Review: based on 6 reviews. Customer Review: I bought this book about 6 months ago to prepare for a projected move to the JBoss AS from Websphere. As with most technical books I read as much as I needed for the tasks at hand. My project seems to be cancelled, so I may not go back to this book, but I'd like to leave this review. I believe this is the only book targeted at JBoss ...
