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.

To start, here are three criteria from [...]

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 are [...]

When you use a transparent persistence interface like JDO with an object database, there
is no need for data conversion (or mapping) from tables to objects
and back. Both the Enterprise Java Beans (EJBs) and the database use the same
object model. This is illustrated in
the diagram where it indicates that no data conversion is needed.

JBoss in Action: Configuring the JBoss Application Server by Javid Jamae, Peter Johnson Average Customer Review: based on 4 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 ...

WebSphere Application Server Administration Using Jython by Robert A. Gibson, Arthur Kevin McGrath, Noel J. Bergman Average Customer Review: based on 4 reviews. Customer Review: I was introduced to this book during a Jython class taught by Keven McGrath. He kept referring to the book in the classroom, and bringing up sample pages for examples. I was favorably impressed during the class, and even more so when the book finally arrived. They take a very important subset of Jython code for WebSphere and give con...

70-643: Windows Server 2008 Applications Infrastructure Configuration, Package (Microsoft Official Academic Course Series) by Microsoft Official Academic Course Average Customer Review: based on 1 review. Customer Review: Decided to buy the MOC (MS Official Curriculum) for this test. Didn't find it worth the money. Seemed to be a longer read than the Sybex books (although didn't use the Sybex book for this exam so I can't say how it would compare). Text was well written and easy to understand. It was written for a newbie to network admin role. I was up...
