brianlange Posted November 29, 2010 Share Posted November 29, 2010 I'm working with the zend framework. I've implemented the quickstart tutorial that uses that data mapper pattern. I am now reading about using a service layer. Does the service layer serve as the mapper class? In other words are they exclusive? Or could an application have both a service layer and a data mapper class?

ignace Posted November 30, 2010 Share Posted November 30, 2010 They are not mutually exclusive. A Service Layer could use a Data Mapper for example. A Service Layer encapsulates your services like a Facade encapsulates your sub-system(s).

shlumph Posted November 30, 2010 Share Posted November 30, 2010 Exactly what ignance mentioned. Your service layer should handle model creation. It should pull a lot of that logic out of your controllers. If you want, you can take a look at an example I have on github: https://github.com/rkeplin/Blog/tree/master/application/services/ Link to comment https://forums.phpfreaks.com/topic/220161-service-layer-and-the-data-mapper-pattern/#findComment-1141361 Share on other sites More sharing options...
