Dave, I have had some family things come up and will not be able to make the meeting. I am bummed as I really like your topic and know I am going to be missing out. Is there a chance you would be willing to post your presentation so I can review it online and at least learn part of what you are sharing?
Thanks, Tom -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Matt Woodward Sent: Monday, May 08, 2006 10:35 AM To: Dallas/Fort Worth ColdFusion User Group Mailing List Subject: [DFW CFUG] Meeting Tomorrow! Tomorrow's meeting will be at TEKsystems and we'll get started at 6:30 pm. Dave Shuck will be presenting on "Subclassing Data Components for Flexible Applications." I also still have some Adobe schwag to give away, so be there! DAVE SHUCK: SUBCLASSING DATA COMPONENTS FOR FLEXIBLE APPLICATIONS One of the advantages that you hear repeatedly of a good OO design, using DAO and Gateway patterns is the database abstraction. One benefit of database abstraction is that your application is not tied to a specific database architecture. This means that if you suddenly need to uproot your site and move to a different database, you do not have countless queries buried throughout your code. If you followed the rules and followed the patterns, then you simply need to alter the code that persists your data in the DAO and Gateway objects. But what if you are building an application that you know will sit on several different databases or use different methods for data persistence? One method would be to create subclasses of your DAOs and Gateways that deal with specific persistence needs. I will be showing a simple example mini-application I wrote that will demonstrate how the database has a somewhat insignificant role in an OO system. We will be running the same code on top of three data persistence methods: 1) MS SQL with stored procedures, 2) MySQL with plain SQL, and 3) Encrypted WDDX text files (Why? Because we can!). -- Matt Woodward [EMAIL PROTECTED] http://www.mattwoodward.com _______________________________________________ Reply to DFWCFUG: [email protected] Subscribe/Unsubscribe: http://lists1.safesecureweb.com/mailman/listinfo/list List Archives: http://www.mail-archive.com/list%40list.dfwcfug.org/ http://www.mail-archive.com/list%40dfwcfug.org/ DFWCFUG Sponsors: www.HostMySite.com www.teksystems.com/ _______________________________________________ Reply to DFWCFUG: [email protected] Subscribe/Unsubscribe: http://lists1.safesecureweb.com/mailman/listinfo/list List Archives: http://www.mail-archive.com/list%40list.dfwcfug.org/ http://www.mail-archive.com/list%40dfwcfug.org/ DFWCFUG Sponsors: www.HostMySite.com www.teksystems.com/
