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 Object Request Broker (ORB) is middleware that uses the CORBA specification.
The Object Request Broker or ORB takes care of all of the details involved in routing a request from client to object, and routing the response to its destination.
The ORB is also the custodian of the Interface Repository (abbreviated variously IR or IFR), an OMG-standardized distributed database containing
OMG IDL interface definitions.
On the client side, then, the ORB provides interface definitions from the IFR, and constructs invocations for use with the Dynamic Invocation Interface (DII). It also converts Object References between session and stringified format, and (for CORBA 2.4 and later ORBs) converts URL-format corbaloc and corbaname object references to session references.
On the server side, the ORB de-activates inactive objects, and re-activates them whenever a request comes in. CORBA supports a number of activation patterns, so that different object or component types can activate and de-activate in the way that uses resources best.

The CORBA Reference Guide: Understanding the Common Object Request Broker Architecture by Alan Pope Average Customer Review: based on 3 reviews. Customer Review: This is a good book for those who understand client/server or OO programming, but who haven't had exposure to CORBA. The book doesn't give enough depth to serve as a developer's reference guide. But, if you want a solid understanding of all aspects of CORBA without having to read through a 3-inch thick book, this is the book to pick.
