Some of you might recall that I wrote a tutorial for Object-Ordiented ColdFusion Programming (OOP) beginners a while back, and now i have part 2 on line.
The reason for the tutorial in the first place was that I realised quite a few beginners to OOP were swamped by the language rather than the concepts. There were so many new terms to learn, and such a convoluted maze of explanations that it all became quite overpowering for me anyway. Every time I thought i had got my head around it, some new term would emerge, telling me I still had a lot of learning to do. And every new term seemed to require half a dozen more new terms to explain it. So I set about trying to explain the OOP concepts without all those terms. Explain it in ways that procedural programmers could understand, and along the way, pick up some of the essential concepts without all the confusing terminology. Part 1 of the tutorials set up a simple application, manipulating records from a database using objects rather than the way you might have done it in the past. It showed how to separate out all the database activity into a separate cfc of its own, how to reuse a form for multiple purposes, how to make sure that cfcs didnt have to access any scopes they didnt need to, and some other concepts too. Part 2 is now on line at http://afpwebworks.com/index.cfm?pid=111328. You can download the code and follow along with the tutorial. This part introduces the bean - explains one way to build one, what all the parts do, and rebuilds the application from part 1 using the bean to hand around the data your applicatoin needs. At the end of the two parts, you should be able to build quite sophisticated applications of your own, you'll be using at least one automatic code generator to write a lot of the code for you, you'll be reusing forms, and understand some of the OOP language - words like encapsulation, persistence layer, DAO, etc. After working through the two easy-to-read tutorials, you should be confident in understanding the more sophisticated writing of the OOP experts, and be less confused by all the terminology. Let me know what you think of the tutorials. Perhaps i might write more if this second one gets as much readership as the first did! -- Cheers Mike Kear Windsor, NSW, Australia Adobe Certified Advanced ColdFusion Developer AFP Webworks http://afpwebworks.com ColdFusion, PHP, ASP, ASP.NET hosting from AUD$15/month ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;203748912;27390454;j Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:310925 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
