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!”
Software Engineering: How do you start?
There are interesting challenges in applying the art and science of Engineering Disciplines to Software Analysis and Design. If we accept the notion that we need as complete a collection of Requirements as possible either for a full blown application solution (change or new) or a SPRINT to add functionality to either an existing applicationContinue reading “Software Engineering: How do you start?”
Let’s CLOUD the Issue..
I just read an article about the word “CLOUD” being more of a verb than a noun so I thought I would add my two cents to this discussion and Cloud the issue some more. This article was written by someone in a networking group that I have attended in the past and I will,Continue reading “Let’s CLOUD the Issue..”
Structure Programming – Advice from IT.Toolbox
The only point I disagree with in this article is about replicating code for readability! DO NOT REPLICATE code ’cause it also replicates Maintenance Costs! Other than that – Bravo to the author: Craig Borysovitch! http://it.toolbox.com/blogs/enterprise-solutions/systems-development-structured-programming-guidelines-48980 bgbg
Orthogonal Views…

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…”
Input – Process – Output
What exactly should a computer program do? How will you know if the program you have written or requested to be written for you does what you need it to do? It’s really a whole lot simpler than you might think. If you, as a business user, can define what information is available to accomplishContinue reading “Input – Process – Output”
Syntax of an ERD – Entity Relationship Diagram
Syntax Rules for an Entity Relationship Diagram: An Entity Relationship Diagram Sample: Use this link: https://docs.google.com/drawings/d/1keA4BzVCJXcUoNWDw7-0pIrQ7AsB5CgavjWR7P5Wyrg/edit?hl=en_US (may have to paste into a browser) Business Rules derived from this sample are: It is also interesting to note that since there is no relationship between Customer and Product there are no Business Rules that can be derived betweenContinue reading “Syntax of an ERD – Entity Relationship Diagram”
Process Modeling
Flowcharts, Data Flow Diagrams, Swim Lane diagrams, Use Cases and other constructs have been used to reflect what a Business or Systems Analyst thinks the client is describing when they talk about Business Process and the use of information in the conduct of their business. These diagrams have structure, syntax, and rules that have beenContinue reading “Process Modeling”
Modeling for Money!
One of the basic principles of Software Engineering is the creation of visual models to demonstrate the project team’s understanding of the discoveries we are collecting from the users who are driving our discussions. The type of drawings were proscribed by several authors of the time but regardless of the style of the drawing, theyContinue reading “Modeling for Money!”
