experimenting with Cockburn use cases in code I was writing some complicated UI code. I decided to employ Cockburn use cases with fish,kite,and sea levels (discussed by Martin Fowler in his book 'UML Distilled'). I wrapped Cockburn use cases in static C# objects so that I could test logical conditions against static constants which r...
I have read in Patterns of Enterprise Application Architecture that a Unit Of Work should only be used in a single Session. So each session should have its only Unit Of Work. Can anybody tell me why I could not use one Unit Of Work for the whole application (in my case ASP.NET). thx, Lieven Cardoen aka Johlero ...
Ok so I've implemented both REST and SOAP services and I like both depending on the context. For me, WS* is great when I want an explicit contract between the server and the client e.g. for sensitive information or for mission critical stuff. REST on the other hand whilst flexible in terms of the schema definition, is in my mind more ide...
Having read Fowler's "Refactoring" for a while, I still often catch myself thinking "I should have done this in smaller steps." -- even when I did not broke my code. Refactoring in small steps is safe, but cost time. It's a trade off between speed and risk -- I try to be strategic in choosing the way how I am refactoring. Nevertheless:...
Hi, I'm thinking of buying Martin Fowler's "Patterns of Enterprise Application Architecture". From what I can see it seems like a great book, it an architectural book with bias towards enterprise Java -- just what I need. However, in computer years, it is quite old. 2003 was a long time ago, and things have moved on quite a bit since t...
I have been utilizing the Fowler patterns for domain models with a Data Mapper and have run into some confusion on how to implement the creation portion of CRUD. I can't utilize existing ORM technologies as the underlying data sources are custom systems. The area that’s troubling me is how to call the underling ORM when I need to create ...
I'm basing this question on Fowler PoEAA. Given your familiarity with this text, aren't the ViewModels used in ASP.NET MVC the same as DTOs? Why or why not? Thank you. ...
Why does Fowler PoEAA p. 498 define the null-object pattern in the following way (sample shortened, language is c# but doesn't matter): public class Customer { public virtual string Name {get; set;} } public class NullCustomer : Customer, INull { public override Name { get { return "ImTheNull";} // setter ommitted } ...
Hi, I've read xUnit Test Patterns. http://martinfowler.com/books.html There is 'Churchillian knock-off' expression in Martin Fowler's writes like this... If you go to junit.org, you'll see a quote from me: "never in the field of software development have so many owed so much to so few lines of code". JUnit has been criticized as a minor...
