Presentation Model vs Passive View

由 匆匆过客 提交于 2019-12-23 18:29:51
问题 i am wondering about the difference between the two mentioned patterns. when you consider, that you need synchronization code in the presentation model pattern and that code is in the presentation model itself, then i think the patterns are quite similar. Both delegate events to the presentation model / presenter. presentation model and presenter command the domain model and do also observe the domain model. on occuring changes, they both sync with the view (since the synchronisation code in

问题 I'm sharing data via RIA services using a presentation model on top of LINQ to SQL classes. On the Silverlight client, I created a couple of new entities (album and artist), associated them with each other (by either adding the album to the artist's album collection, or setting the Artist property on the album - either one works), added them to the context, and submitted changes. On the server, I get two separate Insert calls - one for the album and one for the artist. These entitites are new

How best to implement support for multiple devices in a web application

由 荒凉一梦 提交于 2019-12-11 17:52:32
问题 My client would like a business application to support 'every possible device'. The application in question is essentially a web application and 'every possible device', I believe encompasses mobile phones, netbooks, ipad, other browser supporting devices, etc. The application is somewhat complex w.r.t. the data it captures and other functions it performs (reporting). If I continue to honor increasing complexity in the application, I guess there are more chances of it not working on other

What are the differences between Presenter, Presentation Model, ViewModel and Controller?

由 不羁岁月 提交于 2019-11-29 19:05:31
I have a pretty good idea how each of these patterns work and know about some of the minor differences between them, but are they really all that different from each other? It seems to me that the Presenter, Presentation Model, ViewModel and Controller are essentially the same concept. Why couldn't I classify all of these concepts as controllers? I feel like it might simplify the entire idea a great deal. Can anyone give a clear description of their differences? I want to clarify that I do understand how the patterns work, and have implemented most of them in one technology or another. What I
