Another MVC Application: Introduction</h2>
<span style="color: #253340; font-family: 'Segoe UI', Tahoma, Arial, Helvetica, sans-serif; font-size: 13.0080003738403px; line-height: 19.0176963806152px;">All websites are growing faster these days, and once it grows, it is very hard to write, organize and maintain. As we add new functionality or developer to a project, any large web applications with poor design may be go out of control. So the idea behind this article is to design a website architecture that must be simple, easily understandable by any web designer (beginner to intermediate) and Search Engines. For this article I am trying to design a website for any individuals to maintain their contact details online. However, in future, the same application could be used by large community all over the world with added functionality and modules. So, the design should be easily adaptable in order to cope with the future growth of business.</span><br />
<br style="color: #253340; font-family: 'Segoe UI', Tahoma, Arial, Helvetica, sans-serif; font-size: 13.0080003738403px; line-height: 19.0176963806152px;" />
<span style="color: #253340; font-family: 'Segoe UI', Tahoma, Arial, Helvetica, sans-serif; font-size: 13.0080003738403px; line-height: 19.0176963806152px;">In this article I will talk about creating and designing User Interface (UI) in such a manner so that UI will be separated from the business logic, and can be created independently by any designer/developer. For this part we will use ASP.Net MVC, Knockout Jquery and Bootstrap. later in this article we will discuss more about database design and implementing business logic using structured layers using SQl Server 2008, Entity Framework, and Castle Windsor for Dependency Injection.</span><br />
<h2 style="background: rgb(240, 241, 244); border: 0px; color: #253340; font-family: 'Segoe UI Semibold', Segoe-Semibold, Tahoma, Arial, Helvetica, sans-serif; font-size: 1.308em; font-stretch: normal; font-weight: normal; height: 40px; letter-spacing: 1px; line-height: 1.923em; margin-bottom: 15px !important; margin-left: 0px; margin-right: 0px; margin-top: 20px !important; outline: 0px; padding: 1px 0px 3px 14px; vertical-align: baseline; width: 636px;">
Separation of Concern: Primary Objective</h2>
<span style="color: #253340; font-family: 'Segoe UI', Tahoma, Arial, Helvetica, sans-serif; font-size: 13.0080003738403px; line-height: 19.0176963806152px;">The key concept is stripping out most or all logic. Logic should not be bound to a page. What if we need to re-use the logic from one page in another? In that case we will be tempted to copy-and-paste. If we are doing this then our project will become maintainable. Another important concept is to separate data access layer from any business logic, as we are planning to use Entity Framework this is less of a problem as EF should already have this end separate. We should be able to easily move all our EF files to another project and simply add a reference to the projects that need it. Below is the high level design:</span><br />

Seven Projects in One Solution : Is it required ?</h2>
<span style="color: #253340; font-family: 'Segoe UI', Tahoma, Arial, Helvetica, sans-serif; font-size: 13.0080003738403px; line-height: 19.0176963806152px;">It is all about your decision… The proposed designed will offer some rather relevant benefits, which include:</span><br />
<ul style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; color: #253340; font-family: 'Segoe UI', Tahoma, Arial, Helvetica, sans-serif; font-size: 13.0080003738403px; line-height: 19.0176963806152px; list-style: none url(https://download-codeplex.sec.s-msft.com/Images/v21029/doublearrow.gif); margin: 15px 0px 20px; outline: 0px; padding: 0px 0px 0px 35px; vertical-align: baseline;">
<li style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; font-size: 13.0080003738403px; margin: 0.3em 0px 0.3em 40px; outline: 0px; padding: 0px; vertical-align: middle;">Separation of Concern: Design should allow clear and defined layers; means segregate application into distinct areas whose functionality does not overlap. such that UI-designers can focus on their job without dealing with the business logic (Application.Web), and the core developer can only work on main business logic's (Application.DTO or Application.Manager).</li>
<li style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; font-size: 13.0080003738403px; margin: 0.3em 0px 0.3em 40px; outline: 0px; padding: 0px; vertical-align: middle;">Productivity: It is easier to add new features to existing software, since the structure is already in place, and the location for every new piece of code is known beforehand, so any issue can be easily identified and separated to cope with complexity, and to achieve the required engineering quality factors such as * * robustness, adaptability, maintainability, and re-usability.</li>
</ul>
<span style="color: #253340; font-family: 'Segoe UI', Tahoma, Arial, Helvetica, sans-serif; font-size: 13.0080003738403px; line-height: 19.0176963806152px;">Maintainability: It is easier to maintain application, due to clear and defined structure of the code is visible and known, so it’s easier to find bugs and anomalies, and modify them with minimal risk.</span><br />
<ul style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; color: #253340; font-family: 'Segoe UI', Tahoma, Arial, Helvetica, sans-serif; font-size: 13.0080003738403px; line-height: 19.0176963806152px; list-style: none url(https://download-codeplex.sec.s-msft.com/Images/v21029/doublearrow.gif); margin: 15px 0px 20px; outline: 0px; padding: 0px 0px 0px 35px; vertical-align: baseline;">

</ul>
<span style="color: #253340; font-family: 'Segoe UI', Tahoma, Arial, Helvetica, sans-serif; font-size: 13.0080003738403px; line-height: 19.0176963806152px;">Re-usability: Re-usability is another concern on designing any application, because it is one of the main factors to decrease the total cost of ownership, and our design should consider to what extent we can reuse the created Web application and different layers.</span><br />
<span style="color: #253340; font-family: 'Segoe UI', Tahoma, Arial, Helvetica, sans-serif; font-size: 13.0080003738403px; line-height: 19.0176963806152px;">In last section of this article, we will discuss the functionality of each individual layer’s in details.</span><br />

Part 1: Create Web Application (Knockout.js, Asp.Net MVC and Bootstrap): For Designers</h2>
<span style="color: #253340; font-family: 'Segoe UI', Tahoma, Arial, Helvetica, sans-serif; font-size: 13.0080003738403px; line-height: 19.0176963806152px;">Before kick-off the UI part, let us see what benefits we are getting using Knockoutjs and Bootstrap along with ASP.NET MVC 4.</span><br />
<br style="color: #253340; font-family: 'Segoe UI', Tahoma, Arial, Helvetica, sans-serif; font-size: 13.0080003738403px; line-height: 19.0176963806152px;" />
<b style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; color: #253340; font-family: 'Segoe UI', Tahoma, Arial, Helvetica, sans-serif; font-size: 13.0080003738403px; line-height: 19.0176963806152px; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">Why Knockoutjs:</b><span style="color: #253340; font-family: 'Segoe UI', Tahoma, Arial, Helvetica, sans-serif; font-size: 13.0080003738403px; line-height: 19.0176963806152px;"> Knockout is an MVVM pattern that works with a javascript ViewModel. The reason this works well with MVC is that serialization to and from javascript models in JSON is very simple, and it is also included with MVC 4. It allows us to develop rich UI's with a lot less coding and whenever we modify our data, Immediate it reflect in the user interface.</span><br />
<br style="color: #253340; font-family: 'Segoe UI', Tahoma, Arial, Helvetica, sans-serif; font-size: 13.0080003738403px; line-height: 19.0176963806152px;" />

It comes with bundles of CSS styles, Components and Javascript plugins. It provides Cross platform support, which eliminates major layout inconsistencies. Everything just works! Good documentation and the Twitter Bootstrap's website itself is a very good reference for real life example. And, finally, it saves me plenty of times, as it cut the development time to half with very less testing and almost zero browser issues. Some other benefits we can get by using this framework are:</span><br />

<h2 style="background: rgb(240, 241, 244); border: 0px; color: #253340; font-family: 'Segoe UI Semibold', Segoe-Semibold, Tahoma, Arial, Helvetica, sans-serif; font-size: 1.308em; font-stretch: normal; font-weight: normal; height: 40px; letter-spacing: 1px; line-height: 1.923em; margin-bottom: 15px !important; margin-left: 0px; margin-right: 0px; margin-top: 20px !important; outline: 0px; padding: 1px 0px 3px 14px; vertical-align: baseline; width: 636px;">

<br />
<pre style="background-attachment: initial; background-clip: initial; background-color: rgb(236, 236, 236) !important; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 1px solid rgb(211, 211, 211) !important; color: #253340; font-family: Consolas, 'Courier New', Courier, monospace !important; font-size: 13.0080003738403px; height: auto; line-height: 19.0176963806152px; outline: 0px; overflow: hidden; padding: 0.5em; vertical-align: baseline; white-space: pre-wrap;">var DummyProfile = [

Note that it's a ko.observableArray , and it is the observable equivalent of a regular array, which means it can automatically trigger UI updates whenever items are added or removed.</span><br />
<br style="color: #253340; font-family: 'Segoe UI', Tahoma, Arial, Helvetica, sans-serif; font-size: 13.0080003738403px; line-height: 19.0176963806152px;" />

<br />
<pre style="background-attachment: initial; background-clip: initial; background-color: rgb(236, 236, 236) !important; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 1px solid rgb(211, 211, 211) !important; color: #253340; font-family: Consolas, 'Courier New', Courier, monospace !important; font-size: 13.0080003738403px; height: auto; line-height: 19.0176963806152px; outline: 0px; overflow: hidden; padding: 0.5em; vertical-align: baseline; white-space: pre-wrap;">var ProfilesViewModel = function () {
    var self = this;
    var refresh = function () {
        self.Profiles(DummyProfile);
    };
 
    // Public data properties
    self.Profiles = ko.observableArray([]);
    refresh();
};
ko.applyBindings(new ProfilesViewModel());

We need to use the foreach binding on <tbody> element, so that it will render a copy of its child elements for each entry in the profiles array, and then populate that <tbody> element with some markup to say that you want a table row (<tr>) for each entry.</span><br />

<br />

As we define this array as observable, the UI will be kept in sync with changes to that array. Try it by clicking on Remove button. Edit link and Create Profile button will simply display the alert. So, let us implemented this functionality in next steps:</span><br />

As one profile can have multiple phone of different types, So, we will use the “foreach” binding for Phone numbers data, so that it will render a copy of its child elements for a particular profile, and then assign the appropriate values. Add below section in CreateEdit.cshtml just after Profile Information and before Save button.</span><br />

Validation is the major requirement and now a day’s most ignorant part for any web application. By proper validation, user can know what data needs to be entered. Next in this article, I am going to discuss KnockoutJS Validation library which can be downloaded using NuGet. Let us check some of the most common validation scenarios, and how to achieve it using knockout validation.</span><br />

<img alt="34.png" src="http://download-codeplex.sec.s-msft.com/Download?ProjectName=ddmvc4&DownloadId=604412" style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px; color: #253340; font-family: 'Segoe UI', Tahoma, Arial, Helvetica, sans-serif; font-size: 13.0080003738403px; line-height: 19.0176963806152px; margin: 0px; max-width: 100%; outline: 0px; padding: 0px; vertical-align: baseline;" title="34.png" /><br />

<span style="color: #253340; font-family: 'Segoe UI', Tahoma, Arial, Helvetica, sans-serif; font-size: 13.0080003738403px; line-height: 19.0176963806152px;">Next we will discuss the overall structure for our application, in terms of the logical group of components into separate layers, which communicates with each other with/without any restrictions and each logic has its own goals. Layers are an architectural style, and it resolves the maintenance and enhancement problems in the long run.</span><br />
<br style="color: #253340; font-family: 'Segoe UI', Tahoma, Arial, Helvetica, sans-serif; font-size: 13.0080003738403px; line-height: 19.0176963806152px;" />

<h2 style="background: rgb(240, 241, 244); border: 0px; color: #253340; font-family: 'Segoe UI Semibold', Segoe-Semibold, Tahoma, Arial, Helvetica, sans-serif; font-size: 1.308em; font-stretch: normal; font-weight: normal; height: 40px; letter-spacing: 1px; line-height: 1.923em; margin-bottom: 15px !important; margin-left: 0px; margin-right: 0px; margin-top: 20px !important; outline: 0px; padding: 1px 0px 3px 14px; vertical-align: baseline; width: 636px;">
Application.Common :</h2>
<span style="color: #253340; font-family: 'Segoe UI', Tahoma, Arial, Helvetica, sans-serif; font-size: 13.0080003738403px; line-height: 19.0176963806152px;">This is a class library application, with some common functionality and can be used by different logical layers. For e.g. Security, Logging, Tracking, Validation etc. The components defined in this layer can not only reuse by other layers in this solution, but can also be utilize by other applications. To make it easier to change in future, we can use Dependency Injection and abstraction, with minimal change in our application.</span><br />
<br style="color: #253340; font-family: 'Segoe UI', Tahoma, Arial, Helvetica, sans-serif; font-size: 13.0080003738403px; line-height: 19.0176963806152px;" />

<br style="color: #253340; font-family: 'Segoe UI', Tahoma, Arial, Helvetica, sans-serif; font-size: 13.0080003738403px; line-height: 19.0176963806152px;" />

<h2 style="background: rgb(240, 241, 244); border: 0px; color: #253340; font-family: 'Segoe UI Semibold', Segoe-Semibold, Tahoma, Arial, Helvetica, sans-serif; font-size: 1.308em; font-stretch: normal; font-weight: normal; height: 40px; letter-spacing: 1px; line-height: 1.923em; margin-bottom: 15px !important; margin-left: 0px; margin-right: 0px; margin-top: 20px !important; outline: 0px; padding: 1px 0px 3px 14px; vertical-align: baseline; width: 636px;">
Application.Core:</h2>
<span style="color: #253340; font-family: 'Segoe UI', Tahoma, Arial, Helvetica, sans-serif; font-size: 13.0080003738403px; line-height: 19.0176963806152px;">The components of this layer implement the system core functionality and encapsulate all the relevant business logic. Basically, this layer usually contains classes which implement the domain logic within their methods. This layer also defined a Unit of Work contract within the Core Layer so it will be able to comply with the PI principle. The primary goal is to differentiate and clearly separate the behavior of the core domain/business and the infrastructure implementation details such as data access and specific repositories linked to a particular technology such as ORM, or simply data access libraries or even cross-cutting aspects of the architecture. Thus, by isolating the application Core functionality, we will drastically increase the maintainability of our system and we could even replace the lower layers (data access, ORM, and databases) with low impact to the rest of the application.</span><br />

<h2 style="background: rgb(240, 241, 244); border: 0px; color: #253340; font-family: 'Segoe UI Semibold', Segoe-Semibold, Tahoma, Arial, Helvetica, sans-serif; font-size: 1.308em; font-stretch: normal; font-weight: normal; height: 40px; letter-spacing: 1px; line-height: 1.923em; margin-bottom: 15px !important; margin-left: 0px; margin-right: 0px; margin-top: 20px !important; outline: 0px; padding: 1px 0px 3px 14px; vertical-align: baseline; width: 636px;">

The data persistence components provide access to the data hosted within the boundaries of our system (e.g., our main database which is within a specific BOUNDED CONTEXT), and also to the data exposed outside the boundaries of our system, such as Web services of external systems. Therefore, it has components like “Repositories” that provide such functionality to access the data hosted within the boundaries of our system, or “Service Agents” that will consume Web Services exposed by other external back-end systems. In addition, this layer will usually have base classes/components with reusable code for all the repository classes.</span><br />

<h2 style="background: rgb(240, 241, 244); border: 0px; color: #253340; font-family: 'Segoe UI Semibold', Segoe-Semibold, Tahoma, Arial, Helvetica, sans-serif; font-size: 1.308em; font-stretch: normal; font-weight: normal; height: 40px; letter-spacing: 1px; line-height: 1.923em; margin-bottom: 15px !important; margin-left: 0px; margin-right: 0px; margin-top: 20px !important; outline: 0px; padding: 1px 0px 3px 14px; vertical-align: baseline; width: 636px;">

For each main root ENTITY in our domain, we need to create one repository. Basically, Repositories are classes/components that encapsulate the logic required to access the application data sources. Therefore, they centralize common data access functionality so the application can have a better maintainability and de-coupling between technology and logic owned by the “Manager” and “Core” layers.</span><br />

A Data Transfer Object is an object that is used to encapsulate data, and send it from one subsystem of an application to another. Here we are going to use DTOs by the Manager layer to transfer data between itself and the UI layer. The main benefit here is that it reduces the amount of data that needs to be sent across the wire in distributed applications. They also make great models in the MVC pattern. We can also use DTO’s to encapsulate parameters for method calls. This can be useful if a method takes more than 4 or 5 parameters.</span><br />

For each module we need to declare one Manager. The primary responsibilities of Manager are to accept request from UI/Web layer, then communicate with required repositories and manipulate data based on condition then return back the response. This layer is intermediate between UI and Repositories.</span><br />

It communicates with some methods from manager layer, then evaluate results and choose whether to show an error or page1 or page2 etc. etc. This layer use javascript to load a model for the presentation, but the data is processed in the server through an ajax request, so the server only manage the business logic and the javascript manages the presentation logic.</span><br />
