RE: [CFCDev] DAOs vs Mappers

[RADEMAKERS Tanguy]

as i understand it (that was a warning) you would have one DAO per business object but only one Mapper object for your whole application. You would wind up with code something like   <cfset myOrder = OrderDAO.loadOrder(orderKey)>   vs   <cfset myOrder = Mapper.map.queryForObject("selectOrder",orderKey)>   Check out the iBatis project documentation (ibatis.com) - they provide both a DAO and a Mapper framework (SQLMaps) so there's some discussion there (and in the mailing list archives) about the two approaches.     /t From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Joe Ferraro Sent: Friday, May 27, 2005 4:32 PM To: CFCDev@cfczone.org Subject: [CFCDev] DAOs vs Mappers Can someone give me a brief overview of what the difference is between a mapper and a DAO? They seem somewhat similar. ---------------------------------------------------------- You are subscribed to cfcdev.
