There are many examples of using REST with simple data models. For example a customer with 5 properties and a collection of orders with 6 properties. However I have a hard time visualizing using REST against a model that is more complex -- that you may find in government procurement, finance, medical records management etc. Are there ...
I need your help on the design of the restore-procedure in a backup system I'm building. The prerequisites are the following: A restore can be made of one or several files. A file consists of 1 or more data-blocks (on average 16mb in size, minimum 4mb maximum 64mb). A data-block is replicated using erasure coding into replication-bloc...
When implementing a factory or simple factory, what would go against using a Type instead of an Enum to specify the class to instantiate? For example public class SimpleFactory { public static ITest Create(Type type) { if (type == typeof(ConcreteTest1)) return new ConcreteTest1(); if (type == typeof(ConcreteTest2)) return n...

Hi I have some PHP classes I am creating from XML config. What I would like to know is this: Am I better off (from an object-oriented standpoint) having factory methods to create those classes from XML or passing in XML to the constructor to create the classes? The factory approach has the advantage of separating construction from usa...
We've written a web service which uses a simple entity translator to map the values of DTO back on to "real" server side business objects. As part of this excercise. We have come across an "interesting" distinction between explicitly set null values and clients having not set a value. The problem is essentially that we want to set a def...
I'm looking for a design pattern to manage a pool of objects. A thread can request an object, in my case an object representing a remote host. If the host-object does not exist it is created, added to the pool and a reference returned. If another thread or object requests the same (remote host) object it too is given the reference. If ...

To make things worse, since our project wasn't huge the prof said to combine the Model and Controller. So now that I'm trying to make a sweet project to add to my employability port...
In addition to being a 30 year pattern, MVC was never meant for current applications. MVP was its successor and designed to handle event based apps coming out in the 90s. Passive View and Supervising Controller seem to have risen to the top. For those two, it almost isn't necessary to talk about MVC/MVP. Specifically, is the controll...
