I need some help to organize my data model well. I am writing an app which will be a simple notebook. I use a three-tier architecture = business-logic, data-logic, database access. I`d like to use system of tags so it will be easier to search info in the app. Here are few questions - due to separation of concerns, classes of entities ...
I have been working with ASP.NET MVC for a couple of months now and I'm still not happy with the layout of my project's solution. I am trying to construct a mid-sized website CMS that is as portable and reusable as possible and there are some obvious problems in the design of it. I am looking for some advice regarding how I should struct...
Hi, Who's responsibility is it to encode a string, the model or the view? I've a string from a database, it's come from the user - I want to keep as a much information as possible in the database, so I'm saving the input verbatim. When I come to display the string, should I be encoding it when I populate the view model, or should the ...

The goal is to query a database table of photo albums information and display it grouped by year. The steps are: Query database and return datatable of the database information. Convert Datatable to ...
In a previous question one of the comments from Dr. Herbie on the accepted answer was that my method was performing two responsibilities..that of changing data and saving data. What I'm trying to figure out is the best way to separate these concerns in my situation. Carrying on with my example of having a Policy object which is retriev...

I'm currently working on an ASP.net MVC web site project. I've put all database related stuff in my model, such as queries and update/delete/save functions. I also created a couple of controllers that execute the logic. I added a Helpers namespace and inside that namespace there are a few classes that contain logic for pagination, inte...
Scenario: I have a (numeric) textbox, a button, and a label. When the button is clicked I'd like the label to "animate" to the numeric value in the textbox (like a spinning dial) Given: a) that animations in storyboards cannot have databindings (because they are not FrameworkElements) b) the lack of triggers in Silverlight What is the...
In reading up on ASP.NET MVC I came across some wonderful examples of validation where the business rules were associated with the model and the UI merely displayed the set of errors and flagged the form elements associated with invalid input. I think it makes fantastic sense to keep this logic in a single place rather than have every f...
All the examples I've seen of what and how MVC SHOULD be have used classes as the models, classes as the controller, and HTML templates as the view. And all of them consisted of one index.php script and different requests in the url to run the entire site. So they've all been something like... MODEL class User{ function getUser($u...
In our application we have many Model objects that have hundreds of properties. For every property on the model: public string SubscriptionKind { get; set; } ...100x... we had to make an INotifyPropertyChanged-enabled property on the ViewModel: #region ViewModelProperty: SubscriptionKind private int _subscriptionKind; public int Sub...
Hi, I have seen a few examples where the viewModel (in Silverlight apps) is in the UserControl.Resources XAML section of a View. I read that for using Blend, this is a good place to have it (as it gives the ability to see sample data in Blend). However, is this the best place to have the viewModel? I read that the "view has to push s...

Packaged com.company.model & com.company.persistance Another Utils.jar - contains DateTime, String, Thread, etc general helper classes. This again is included within all of my apps.

After working with ASP.Net MVC, it has me thinking about Rails. I worked with Rails prior, but am a little rusty. ASP.Net MVC tutorials recomment hiding data layer implementation with the repository pattern. This allows easiesr Dependency Injection for Unit Testing, and nice decoupling of the controller from the model implementation. ...
The problem: I have a legacy php app that is coded in no particular style (some OO, function libraries, some templates, no templates), which I am slowly rewriting, cleaning up, and adding to. When I introduced templates to the system, it was immediately evident that that would really clean up and simplify the code a lot because of th...
What is the difference between Single Responsibility Principle and Separation of Concerns? ...
Just began researching mvc, and am not sure I grasp it yet. From what I gather it seems like an implementation of a 3 tier solution ie Model corresponds to DAL, Controller to business logic layer, and View as Presentation layer. Am I way off base here? ...
Hello everyone, I am trying to test my controller and maintain separation of concerns. The first concern is "Who is able to execute which action?" I am using authlogic for authentication and be9's acl9 for authorization. But this should not matter, all my authorization concerns are handled in a before_filter. I am testing such a befor...
Hi, I'm trying to be a better developer... What I'm working with: .Net MVC Framework 1.0 Entity Framework 3.5 I've been doing some reading and I think what i want to do is: Create a repository for each aggregate in the domain. An Order repository for example will manage an Order's OrderItems. Create a service layer to handle busi...
i.e. Is MVP still the next best choice when MVC is not an option? I thought I'd ask this here as I'm sure there are others like me who don't have the luxury of being on a green-field project and want to refactor a webforms UI to better separation of presentation from business objects... I'm working on a legacy application tasked with a...
