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 [...]

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 [...]

The Design Decomposition Blog is written by Doug Barry.
If you want to take advantage of using an ODBMS in the middle tier and have
one or more existing relational databases, you will need to map data from a
relational format to an object format.
This mapping of data can become complex. If
you would code this mapping yourself, the amount of code devoted to
mapping often becomes 30 to 40 percent of your total code. Unfortunately,
that 30 to 40 percent is only mapping, not helping to solving your
business problem. It also adds to the possible defects you may need to fix.
So, if you need to map, consider using an object-relational
mapping product. They will save you time and reduce the number of defects
in your mapping. For more information on object-relational mapping
products, click
here (new window).
An object-relational mapping product is shown at the left of this
figure. It handles the mapping and has a cache much like an ODBMS. Data is
mapped to the ODBMS and from the ODBMS based on the application needs. The
ODBMS provides high-speed performance for the Internet.

C++ Object Databases: Programming with the ODMG Standard by David Jordan Description: In 1991, the Object Database Management Group (ODMG) was formed to define standard interfaces for object databases. This standardization has since been achieved, and the popularity of object databases is on the rise. Similar to using SQL to access a relational database, the ODMG provides a corresponding standard for object databases. This book, technically reviewed by ODMG members,...
