A few weeks ago (May 2018), I started a “Go Fund Me” site to gather some money so that I can publish “The Book” that represents many of the ideas from this blog. The Title of the book will be: “IT’s Lost Art of Software Engineering” and will contain much of what has been postedContinue reading “Time for THE BOOK”

Testing Centric Life Cycle
Could there be such a thing as a Testing Centric Life Cycle? What would it have to look like to be Testing Centric? Wouldn’t we have to ask questions of each Deliverable to prove that it somehow supports what we believe our end goal to be? How would we construct these questions to ask ofContinue reading “Testing Centric Life Cycle”
Watch this space: I’m writing AGAIN!!!
I just want you all to know that I have started writing again. Recently, I have spent a lot of time NOT writing (did have some other things to take care of, and still do), but it appears I have the bug again! So, I want to let all of you, my readers, know thatContinue reading “Watch this space: I’m writing AGAIN!!!”
On Conceptual Modeling: 1984; Brodie, Mylopolous, Schmidt
From a recent review of this book (see Blog Post Title), I have a question: Main Question: Is it more efficient to build the indexes in support of invisible keys or to store this same data in each row of a set of tables? What is an Invisible Key? A row of data must haveContinue reading “On Conceptual Modeling: 1984; Brodie, Mylopolous, Schmidt”
Hello World! Thank You, World!
I’ve been writing random and sometimes organized thoughts in this blog for quite a while now and I just took a closer look at the statistics of people who have read my stuff. So, I want to Thank every one of you who have read my materials and I hope that you all continue toContinue reading “Hello World! Thank You, World!”
The Data Manifesto
All Data Are Protected (ala The Matrix) An Event occurs that is associated with a collection of data attributes that need protection. Each unique Event has a finite list of Data that are expected to occur when a new instance of an Event happens. In almost all cases, that list of Data includes, at least,Continue reading “The Data Manifesto”
Swim Lane Diagrams
Since when did Swim Lane Diagrams take the place of more rigorous Software Engineering Requirements gathering models like: Process Models, Data Relationship Models, State Transition Diagrams, Use Cases and Event Models? I’ve been managing several smaller projects lately and if they have any kind of Analysis efforts and documented Requirements, they are only represented inContinue reading “Swim Lane Diagrams”
What Users Say Translated to Software Engineering!
I need a report that shows me how much I spent yesterday! Not an atypical ‘requirement’ from a business users’ point of view, huh? What do you as a Software Engineer DO with this and similar statements? Let’s start with a couple of questions that we can use to expand and clarify on a statementContinue reading “What Users Say Translated to Software Engineering!”
A current definition provides us this: or·thog·o·nal [awr-thog-uh-nl] adjective 1. Mathematics . a. Also, orthographic. pertaining to or involving right angles or perpendiculars: an orthogonal projection. b. (of a system of real functions) defined so that the integral of the product of any Continue reading “Orthogonal Views…”
Remember Codd and Date?
These were two technology authors who were quoted on the subject of Relational Integrity and a Normalized Data Model. Their ideas of reducing redundancy in the physical data schema and protecting the mandatory relationships between entities took a whole lot of attention about how to create, define, and manage data so that it was safeContinue reading “Remember Codd and Date?”
