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 [...]

I am now also posting on the Cutter Blog. My initial posting is (The Acronym) SOA is (Perhaps) Dead (at Some Companies); Long Live Services. It is a response to Anne Thomas Manes’ SOA is Dead; Long Live Services on her blog at the Burton Group.

The typical definition of an atomic task or process is one that cannot be decomposed further. This is vague and subject to interpretation.

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 am going to expand on their criteria to create a more comprehensive definition of a well-formed business process diagram.
To start, here are three criteria from [...]

The Design Decomposition Blog is written by Doug Barry.
A common way of accessing object data is by navigation, also known as
"traversal." The term is derived from the access patterns for the data
structures that are common with object models. Many times these structures are
"trees" or "graphs." If you would draw one of these data
structures, it might look something like the diagram shown below. Moving from
one node in this graph to another node is navigating or traversing the data
structure. This navigation is built into object programming languages such as
Java or C++.
For coding examples of navigation, see how
to access data using object-relational mapping.
There are nearly 400 pages of articles on this site with over 50 pages on object-relational mapping.
