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 [...]

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.
This example uses the ODMG C++ Binding and the ODMG Object Query Language (OQL).
Other C++ bindings and query languages for object-relational mapping products would be similar.
Notice that all the code is C++, 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.
d_Database db;
d_Transaction txn;
try {
db.open("addressDB");
txn.begin();
// perform query
d_OQL_Query query(
"select x from Person x where x.name = \"Doug Barry\"");
d_Bag<d_Ref<Person> > allDougBarrys;
d_oql_execute(query, allDougBarrys);
d_Iterator<d_Ref<Person> > iter = allDougBarrys.create_iterator();
// iterate over the results
d_Ref<Person> p;
while( iter.next(p) ){
// do some addition processing on the person (not shown)
// now traverse to the address object and update its value
p->address.street = "13504 4th Avenue South";
}
