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.
To start checking the class hierarchy, look at the Support Class. It inherits
the Name and Date of birth attributes from the Person Class. It also inherits
Hire date from the Employee Class. Querying the Support Class in the object
schema would, therefore, provide exactly the same results as shown in the relational
schema Support View (new window) if the
same data were stored in the object class definition. This is shown below.
There are nearly 400 pages of articles on this site with over 50 pages on object-relational mapping.

Pro LINQ Object Relational Mapping in C# 2008 by Vijay P. Mehta Average Customer Review: based on 11 reviews. Customer Review: I am not sure what the 2 and 3 star reviews are about, because I thought this book was excellent, and considering the book says "intermediate" I'm not sure why people were expecting a "deep technical ORM, LINQ to SQL, or EF" book. The book is broken into 5 different parts: Part 1 - ORM Concepts - This is really good background for p...
C++ Database Development: Featuring Parody the Persistent Almost-Relational Object Database Management System by Al Stevens Average Customer Review: based on 1 review. Customer Review: Al Stevens, C++ Database Development (MIS Press, 1992) Two questions come to mind as to why anyone would be reading a ten-year-old book on database development in an outdated edition written to cater to an operating system that (almost) no longer exists in any meaningful way. (Or why they would be reading a review of such a book.) Tho...
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...

Customer Review: Bought it used, was supposed to be in perfect condition, but had a little wear and tear here and there. Still in great condition and worth the rebate, shipping was also much fast than what was initially indicated.
