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”

Standards for Cloud Computing

I believe things get “REAL” when there are standards and guidelines for those practitioners who are interested in moving things forward. I found this article talking about creating standards for Cloud Computing and I agree whole-heartedly! http://serion.co.nz/blog/hybrid-and-cloud-computing-standards Thanx for reading and enjoy the article. If you can, be prepared to join the debate. bgbg

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”

Starting your own PMO

If your organization does not have a PMO or has one that has been disappointing in its benefits, then this discussion may be for you! I have an opinion that there are “Five ‘P’s in PMO”: Project, Program, Portfolio, Process, and People.  Others don’t necessarily agree with me but then they are not writing THISContinue reading “Starting your own PMO”

Project in Recovery (not THAT Recovery!)

When a project has been close to failure and shut down is not an option then my repetitive approach to resolving the remaining issues usually goes something like this: Agree on the Recovery Project Charter Scope Objectives Budget Staff List of Open Risks, Issues, Change Request (preferably these lists will be placed in Recovery ProjectContinue reading “Project in Recovery (not THAT Recovery!)”

Project in Trouble?

Despite all of our best efforts, some projects end up in trouble and they need to be ‘saved’ or ‘shut down’! Making the ‘shut down’ decision is very difficult but must be considered once a project that is in trouble is identified.  Some of the questions I have used in the past to determine whetherContinue reading “Project in Trouble?”

What do seven Y’s spell??

REQUIREMENTS! When someone tells you they have a need, you should be able to investigate that original statement with about seven (7) Why’s before they get bored or frustrated with your interest. I need a daily spending report! Why Daily? Why only spending? Why only ONE day? Why not a Rolling Daily Report of 5Continue reading “What do seven Y’s spell??”

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!”
