Summary

Bob Martin of Object Mentor presents the first of his five principles of agile design. Beginning with an explanation of the real purpose of object-oriented design - the management of dependencies - Bob walks through a code example to illustrate how dependencies can be managed with abstractions, and that good designs are those in which high-level abstractions do not depend on low-level details.

Bio

"Uncle" Bob Martin helped create the Agile Manifesto, is a leading authority on Agile software development, and has authored books on Agile Programming, XP, UML, O-O Programming, and C++. Bob is the founder, CEO, and president of Object Mentor, whose professionals provide process improvement consulting, o-o design consulting, training, and development services. http://www.objectmentor.com/

  • Covered only one of five principles???

    by Jean W,

    I was excited when I saw the summary of this video because I've been trying to get my co-workers to read about the five SOLID principles of OO design in the "Agile Software Development" book. I hoped I could email them a link to the video, and it would get them interested enough to read the book.

    Unfortunately, I don't think this video will serve that purpose. First, the principles don't start until minute 20. I can get around that problem by telling my co-workers to just jump ahead to minute 20.

    However, then the video covers only one of the five principles, the Single Responsibility Principle, before ending in the middle of the talk. (It introduces the 2nd principle, the Open/Closed Principle, but doesn't finish covering it.) The video says it had to end because the presentation shifted into tutorial mode, so I understand why it ended. But for my purposes, that makes it useless. I'm not goint to email around a link for a video that covers only one of five principles...

    I hope a version of this presentation can be made as a talk rather than tutorial, introducing all five principles in 20 to 30 minutes (with a strong preference for 20 minutes). The goal would not be in-depth understanding but rather offering just enough insight to entice people to read the book. That's the kind of link I would send around to my co-workers. Thanks!

    Yes it can be downloaded. Use RealPlayer. However, that still doesn't cover the slides, unfortunately.
