I was recently given the task of rebuilding an existing RIA. The new RIA that I've designed is based on Silverlight, with a WCF service to connect to MS SQL Server. This is my first time doing something like this, so I'm not sure how to design the entire thing. Basically, the client can look through graphs of "stocks" (allowing the cl...

I'm looking for input on the best way to refactor the data access layer (DAL) in my PHP based web app. I follow an MVC pattern: PHP/HTML/CSS/etc. views on the front end, PHP controllers/services in the middle, and a PHP DAL sitting on top of a relational database in the model. Pretty standard stuff. Things are working fine, but my DAL is...
When I look at ASP.NET MVC projects I everytime see loose coupled architecture. For what do I need a loose coupling in a web architecture (if I do not make unit tests)? What are advantages and disadvantages of this? ...
... and I did the first web application using it, now I'm going to create the second. In this first web application I enhanced the framework's core library with new things and promptly updated framework branch. I'm using bazaar to keep framework and web application committed. The application was in the beginning, a full branch of frame...
Hi. I am a trainee developer and have been writing .NET applications for about a year now. Most of the work I have done has involved building new applications (mainly web apps) from scratch and I have been given more or less full control over the software design. This has been a great experience however, as a trainee developer my confi...
I realize there have been a few other questions on this topic, and the general concensus is to use your language of choice to manipulate the XML. However, this solution does not quite fit my circumstances. Firstly, the scope of the project: We want to develop platform independent e-learning, currently, its a bunch of HTML pages but as t...
I have created a class library (assembly) that provides messaging, email and sms. This class library defines an interface IMessenger which the classes EmailMessage and SmsMessage both implement. I see this is a general library that would be part of my infrastructure layer and would / can be used across any development. Now, in my appli...
I'm getting the following error when I attempt to compile my XCode project to debug on my device. No architectures to compile for (ARCHS=x86_64, VALID_ARCHS=armv6 armv7). I've included ObjectiveFlickr in my project just as the readme describes. I've gone through the process several times and redownloaded objectiveFlickr a few times t...
I'm maintaining an application which currently is just a web service (built with WCF) and a database backend. The web service is built in layers with a linq-to-sql data access part with core functionality in an own assembly and on top of that the web service assembly which contains the WCF code. The core assembly also handles all busines...
When building a WCF service for a large scale application, which is better: In both cases, assume that the business logic layer is separated into a different assembly. Using your business logic layer as a service implementation i.e. with no code behind and no wrapper <%@ ServiceHost Language="CS" Service="MyApp.BusinessLogic.BusLogi...
When developing an application using agile techniques, what if any initial modelling/architecture activities do you do, and how do you capture that knowledge?? I'm not after a bullet list about XP, Scrum, Crystal, DSDM..etc as I'm familiar with the methodologies. But what do you do above and beyond the guidance given by these. I find I...
We have several applications that are installed in several departments that interact with database via Intranet. Users tend to use weak passwords or store login/password written on a sheets of paper where everybody can see them. I'm worried about login/password leakage & want to minimize consequences. Minimizing database-server attack s...
We have several legacy & 3'd-party systems in organization that use several RDBMS vendors (& more specific data storages). Cross-system data reporting (as well as extra-reports that are not implemented in 3'd-party systems) is required with charts and population of templates (winword, excel). Reporting system is visioned as intranet web-...
Hi all, I was wondering if anyone knew of any simple code implementations of the following architectural patterns (in Java or C#): * Blackboard (passive & active) * Presentation Abstraction Control (PAC) * MVC Thanks in advance ...
We have a considerable code base with relatively high test coverage for pages/forms, all via vanilla POST/GET. Now, we are find ourselves moving more into the 'ajaxy' space, and it's not quite possible to test with GET/POST complete scenarios like user registration, or an item creation, as they involve lots of JavaScript/Ajax calls. Wh...
I have been experimenting recently with Silverlight, RIA Services, and Entity Framework using .NET 4.0. I'm trying to figure out if that stack makes sense for use in any of my upcoming projects. It certainly seems like these technologies can be very productive for developing applications, but I'm struggling to decide how an application...
I'm currently developing an app which will use a Linq to SQL (or possibly EF) data access layer. We already have a database which holds all our Contacts information, but there is currently no API around this. I need to interact with this DB from the new app to retrieve contact details. I can think of two ways I could do this - 1) Develo...
Could a Distributed Hash Table be used for a two-way web app with a pub/sub type application? I'm investigating building a forum type application but with a DHT architecture and P2P (although a central lookup server would be OK to improve performance). Think of a Gnutella/Kazaa type application on the client side but, rather than hittin...
I am reasonably good with CSS. However, when working with someone else's CSS, it's difficult for me to see the "bigger picture" in their architecture (but i have no problem when working with a CSS sheet I wrote myself). For example, I have no problems using Firebug to isolate and fix cross browser compatibility issues, or fixing a floa...
