Day 7 June 26, 2007

Today is Tuesday June 26, 2007. In class we went over a D-Matrix which is short for Design Matrix. What is funny at the moment is the used book named Software Design written by David Budgen. I’m reading this and get to this page where the other person whom owned this book before me used a book mark with three raisens! I got to that page and looked and asked myself what is that and why are there raisens in my book?? LOL Maybe that person before me was eating them and they got on that page or a pack of raisens in that persons book bag broke. I purchased used books before but never got three raisens smashed on a page. LOL

    So back to the D-Matrix concept is a mathmatical matrix that shows a description of design states. It is a very compact notation but looks complex all on it’s own. I’m more used to a flow chart approach top down and not a D-Matrix.
