Re: [CFCDev] Service layer hierarchy

[Ron Phillips]

Would it seem less redundant if the gallery service had a deleteGalleryItems() (plural) function instead?   I am really asking for my own sake, as well — service layers are new to me, but it looks like a structure I might use for a current project.   Ron >>> [EMAIL PROTECTED] 3/17/2006 9:16 PM >>> I've been starting to use service layers in my applications (mostly with mach-ii) and I like how it gives me more flexibility as it hides a lot of the complexity (DAO, Gateways etc) from the controller but I have a couple questions regarding the best way to handle services within other services. I am building a simple image gallery app which consists of two main services, one is the imageService which handles individual gallery items (thumb and larger image) and then I have the galleryService that manages the actual galleries (creating, naming, sorting items etc). Now, should I be using my controller to manage each of these two services seperately (which is what I currently do with my mach-ii listeners) or should my gallery service contain an instance of the image service and therefore all access to the image service be provided through the gallery service? I am starting the think that the latter is the way to go but it seems like I have some redundancy in methods if I call a function called deleteGalleryItem() from galleryService which just calls the deleteItem() function from within imageService, where I could have just directly called deleteItem() from imageService if I handle them separately.
