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.

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.

The Design Decomposition Blog is written by Doug Barry.
This section contains examples of how to access data in a relational database
using object-relational mapping with transparent persistence. The examples show the code needed to perform the operations illustrated
by the animation of transparent
persistence (new window).
The code opens a database, starts a transaction, executes a query to find a
Person object named "Doug Barry," does some further processing on that
object, traverses to an Address object, updates the street of the Address
object, commits the
transaction, and closes the database. Also see transparent
persistence vs. JDBC call-level interface (new window).
Examples of relational database access using transparent persistence can be found
using the following links:
There are nearly 400 pages of articles on this site with over 50 pages on object-relational mapping.

Foundation for Object / Relational Databases: The Third Manifesto by C. J. Date, Hugh Darwen Average Customer Review: based on 4 reviews. Customer Review: Mr. Data and Mr. Darwen have much to say in this book. The question is will community of "database" people read it, assimilate it, and get to sufficient mass to discuss the merits of the concepts described in this book? And, if that does happen, will it be too late to implement any of the concepts in a real DBMS? There is no question...
