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 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 [...]

Object databases can be a way of staging data for your C++ or Java
applications. This example shows two existing data sources that have data in
non-object formats (flat file and relational, for example). The non-object data
is mapped into object models and stored in the object database. This object
database now holds some part of the existing data and perhaps some of its own
data that did not exist previously. At some later time, the object application
can obtain this data and tap the high performance that an object database provides.
This performance is a result of having the same model in the object database as is
used by the object application. See one
model to reduce development and maintenance costs (new window).

Figures, exemples, syntax of codes and clear explanations lead the learner through theory towards practice. Exemples are often very nice.
