Is it ok to roll your own localization framework? I would be ok using the default .NET localization behavior (i.e., putting text in resource files named a certain way in the assembly), except that we have localized images and text that need to be rendered in DirectX in addition to WinForms and WPF. I could put form-specific strings in ...

I am starting out with web development under Java EE and spring and have a high level design question: I have a basic shell set up: I have coded some domain objects (mainly getters and setters for various object attributes which I ultimately want displayed on the page). I am wondering what the proper way to tie everything together is on...

I am designing an ASP.NET MVC application using the Onion Architecture described by Jeffrey Palermo. It is an ASP.NET MVC 2.0 project, where I am requiring that all views be strongly typed using dedicated View Models -- we will not be passing domain models to our views. We are using AutoMapper to do the translation -- AutoMapper is isol...
Considering the regular characteristics of an n-tier app with layers like: presentation, business, data access; how is this normally rebuilt to make a Service-Oriented Architecture (SOA)? Seeking high level overview from programmers experienced in this exercise. To a degree I picture it conceptually flattening out rather than having ...
While architecting any n-tier intranet applications, do I have to consider anything about firewalls in the organization? Are there any special considerations which needs to be proactively addressed or it could be an afterthought. ...
Looking for suggestions/best practices on managing error codes and messages in a multi-tiered applications. Specifically things like: Where should error codes be defined? Enum? Class? How are error messages or further details associated with the error codes? resource files? attributes on enum values, etc.? If you have a multi-tier app...
Rather a simple question. But the implications are vast. Over the last few weeks I've been reading a lot of material about n-tier architecture and it's implementation in the .NET world. The problem is I couldn't find a relevant sample for Winforms with Linq (linq is the way to go for BLL right?). How did you guys manage to grasp the n-...
I would like some advice on the best approach to use in the following situation... I will have a Windows Application and a Web Application (presentation layers), these will both access a common business layer. The business layer will look at a configuration file to find the name of the dll (data layer) which it will create a reference t...
I am new to mocking and dependency injection and need some guidance. My application is using a typical N-Tier architecture where the BLL references the DAL, and the UI references the BLL but not the DAL. Pretty straight forward. Lets say, for example, I have the following classes: class MyDataAccess : IMyDataAccess {} class MyBusines...
In an N-Tier app you're supposed to have a business logic layer and a data access layer. Is it bad to simply have two assemblies: BusinessLogicLayer.dll and DataAccessLayer.dll to handle all this logic? How do you actually represent these layers. It seems silly, the way I've seen it, to have a BusinessLogic class library containing class...
We develop mostly low traffic but highly specialized web applications. Normally we use L2S, EF or nHibernate as access layer and then throws Asp.Net MVC to it and in which for normal crud operations we query the ISession/DataContext directly but for more advanced functions/side effects we put it in a some kind of service layer. Now, i ...

I'm dealing with the 3-tier architecture PHP website. Now,i need to redesign it to suрроrt distributed n-tier architecture.After long hours of research i came to this solution: business logic should be separated into presentation and purely business logic tier to allow for n-layer architecture(user-interface,presentation tier,b.logic an...
Hi gang, We are moving to SSO in our N-tiered SOA applications. If all the services were SOAP, I'd be ok with just the WS-Security, WS-Trust, WS-Federation set of protocols. My problem is that many of the services are RESTful (ironic) and those protocols do not address REST services. What is your advice for SSO protecting the REST se...
