[CFCDev] New to OO, question about inheritance and DAO's

[Boson Au]

Hi, I’m building my first OO app and I have a question regarding inherited classes and how they correspond to DAO’s.   Here’s my situation:   I’m building a pageManager application that basically stores different types of “pages” of a course. Currently there are two types of pages: Lecture and Activity.   This is how they break down:   A generic page has pageID              INT pageTitle           string courseID           INT pageLanguage   INT pageDescription string pageType          INT   a Lecture is a child of page with lectureID           INT lectureNumber   INT faculty(s)           Array(1) of faculty objects   and Activity is a child of Page with activityID           INT activityContent   text       I’m really confused as to how to design DAO’s for this.  I want to be able to have a pageManager cfc that takes a pageID as a field and returns either a lecture or activity object.     Do I build multiple DAO’s that corresponds to each different subclass (ie: a lectureDAO and an activityDAO)?  Do I build one pageDAO that has in its CRUD logic that handles what databases to work with based on the class?     Boson Au Web Content Developer Center for Teaching and Learning with Technology Johns Hopkins University Bloomberg School of Health [EMAIL PROTECTED] 410-223-1671   ---------------------------------------------------------- You are subscribed to cfcdev.
