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. 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 [...]

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 [...]

The Design Decomposition Blog is written by Doug Barry.
This example uses the ODMG Java Binding and the ODMG Object Query Language (OQL).
Other query languages for object-relational mapping products would be similar. Notice that all the
code is Java, with the exception of the query string. You will not find a
database sub-language in this example. The part in blue relates to the animation of transparent
persistence (new window). More
information on the ODMG specification (new
window). Note that the same code would used for object
databases (new
window). Transparent persistent interfaces work with both object
database or object-relational mapping products.
import org.odmg.*;
import java.util.Collection;
Implementation impl = new com.vendor.odmg.Implementation();
Database db = impl.newDatabase();
Transaction txn = impl.newTransaction();
// perform query
OQLQuery query = new OQLQuery(
"select x from Person x where x.name = \"Doug Barry\"");
Collection result = (Collection) query.execute();
Iterator iter = result.iterator();
// iterate over the results
while ( iter.hasNext() )
{
Person person = (Person) iter.next();
// do some addition processing on the person (not shown)
// now traverse to the address object and update its value
person.address.street = "13504 4th Avenue South";
}

Hibernate Made Easy: Simplified Data Persistence with Hibernate and JPA (Java Persistence API) Annotations by Cameron Wallace McKenzie, Kerri Sheehan Average Customer Review: based on 43 reviews. Customer Review: This book is exactly what the title states. It makes hibernate easy. It does not delve into more advanced topics, but that is left for other hiber books. I 1st read Java Persistence with Hibernate and it was too much for me, and I was not able to find another book that did not use xml for configuring hibernate (other than the .cfg.x...
Data Structures and Algorithms in Java (2nd Edition) by Robert Lafore Average Customer Review: based on 24 reviews. Customer Review: This guy does a great job of balancing tech with down to earth understanding. I used this book in my second tier programming class (OOP data structures) and it was the first book that I could really dive into, read his text and then take the code apart and understand it. He has very nice code examples.
Data Structures in Java: From Abstract Data Types to the Java Collections Framework by Simon Gray Average Customer Review: based on 1 review. Customer Review: The book is in fine condition, however it took quite a long time to arrive. When it did arrive, it was wrapped in paper that was barely holding on to the book, and it looked like it encountered some hardships on its journey.
Data Structures and Other Objects Using Java (3rd Edition) by Michael Main Average Customer Review: based on 15 reviews. Customer Review: Even after taking a mid-level CS course where this book was the required text, this book still sits on my bookshelf at work for reference. Why? Well, certainly it is not the most comprehensive book of data structures in existence, nor is it written with a scholarly tone. But, that's the point! Michael Main's writing has the air of a...
