3.   3-Tier / N-Tier Pattern Architecture

The .NET Design Pattern Framework 4.5 comes with a unique pattern reference application named Patterns in Action. It is built on a 4-tier pattern architecture using advanced design patterns and best practices.

Patterns in Action demonstrates, in great detail and with 100% source code, how to build a flexible multi-tier pattern architecture that can support any UI technology, such as, ASP.NET MVC, WPF, and Windows Forms.

Each UI communicates with the application via the exact same service tier (the Facade Pattern). You will receive 4 completely functional applications built with ASP.NET MVC, ASP.NET Web Forms, Windows Forms, and WPF.

See images of each UI platform below:



ASP.NET MVC




ASP.NET Web Forms




Windows Forms




WPF





Did you notice how different these applications are?  And yet, they are:

  1. Built on the exact same multi-tier pattern architecture,
  2. Consume the exact same Service layer, and
  3. Talk to the exact same database.

Quite remarkable!


So how does one build something like this? Below is an image of the Patterns in Action solution which shows the organization of the projects and the layers within the solution.


The red arrows point to the 4 tiers or layers: presentation, service, business, and data (they are numbered 1 through 4).

Inside the presentation layer are 4 different UI platforms, one project for each. What is interesting is that each UI accesses the same service, business, and data layers below.


The next diagram shows the solution as a series of layers.

The Presentation layer supports 4 different UI technologies, two of which are web applications that use the browser. To get to the database, each of the UIs needs to go through the other 3 layers starting with the Service layer and then down via the Business and Data layers all the way to the database.

The Data layer offers 3 different providers to get to the database: ADO.NET, Linq to SQL, and Entity Framework. A web.config value determines which one is used. Swapping out data providers is made easy by using the DAO (Data Access Object) pattern.


Let's look at the many patterns and practices used to build this solution. Here's a graphical overview:

The yellow Convention over configuration box represents a best practice paradigm that is fundamental to the entire solution. Applying convention over configuration greatly simplifies and improves the entire application stack.

Next, we see numerous green boxes with design patterns scattered throughout the solution. They come from three major pattern categories: Gang Of Four patterns, Fowler's Enterprise patterns, and Model-View family of patterns. All are reviewed and discussed in depth in this package.

More about the 'Patterns in Action' application


Patterns in Action is a comprehensive 4.5 .NET reference application that demonstrates when, where, and how design patterns are applied in today's application design.

Of course it comes with 100% source code -- nothing is hidden.

 


The application includes features that are common in modern e-commerce applications. For example, users can browse a product catalog, view products and product details, add items to a shopping cart. Also included is an administrative module in which administrators manage customer data and reports on customer orders with all order details.

However, Patterns in Action is valuable beyond e-commerce applications. Valuable code examples include: a hierarchical menu system, an error logging facility, business rules engine, and a system of a highly configurable data access objects (DAOs).

.NET architects who purchased the Design Pattern Framework tell us they use this application each and every day as an architectural and code reference to their own projects.


Below is an overview of each UI platform in Patterns in Action.






4 & 5.   Sample Application: ASP.NET MVC and Web Forms Patterns

Here are some additional images of the ASP.NET application (both MVC and Web Forms) built on a 4-tier Pattern Architecture.



Product Catalog and Product List




Product Details / Add to Cart




The two projects built with MVC and Web Forms appear and behave the same, but their underlying code is totally different. MVC is based on the MVC (Model View Controller) design pattern, whereas Web Forms is built with traditional code behind pages.






ASP.NET e-commerce application
6.   Sample Application: Windows Forms Patterns

The Windows Forms also consumes the same architecture. It is built with the MVP (Model View Presenter) design pattern. You get to see it all; remember this package comes with 100% source code.



Login to SimpleMembership Service



Customer List with Orders and Order Details






Windows Forms application


7.   Sample Application: WPF Patterns

Next is the WPF application which, again, is built on the same n-tier pattern architecture. This application is built with the popular MVVM (Model View ViewModel) design pattern.

8.   Art Shop -- A fully functional online store

.NET Design Pattern Framework 4.5 doesn't stop with Patterns in Action. New in this release is a web application called Art Shop which is a stylish, production-quality art store that sells art reproductions by famous classic artists like Van Gogh, Cézanne, and Monet.

The Art Shop is built with Spark 4.5, our new rapid application development (RAD) platform. Details on Spark are further below.

First, here is the home page of the Art Shop.


Art Shop Home page




The Art Shop web application includes a store front, shopping cart, checkout page, and order confirmation page. A comprehensive administrative area allows the administrator to view and manage customers and orders. A reporting section is where both pre-packaged and ad-hoc reports are generated. An attractive dashboard page with charts summarizes business performance and statistcs.

Also worth mentioning is that security in the Art Shop is very comprehensive. It includes authorization, authentication, OAuth (with complete Facebook login support), cross-site scripting, and SQL injection.

The store front is particularly interesting. You will learn how to implement common UI patterns including search, sort, filter, and paginate on a single page. Full page refreshes are not required which makes the website super responsive. Partial page refreshes and the use of JavaScript and Ajax are all aspects of building SPA (Single Page Application) solutions. All this and more is covered by this package.

The user experience and usability of an app is greatly affected by how master-detail pages are implemented. In Art Shop these pages actively maintain their browser cache (using JavaScript). This results in very natural page transitions creating a wonderful user experience.

Here are some additional images of the store where users purchase art work -- by the way: Art Shop comes with a fully functional shopping cart.


Art Shop Store Front
(Notice the search, filter, sort, and pagination controls)



Art Shop Product Details Page




Art Shop Shopping Cart





User registration is handled by SimpleMembership with full OAuth support for Facebook.


Art Shop Sign Up with Facebook support





A secure administration area in the application allows admins to maintain users and orders, view and generate reports (pre-configured or ad-hoc), and explore store statistics via a dashboard page with charting.


Art Shop User and Order Administration




Art Shop Dashboard with Charts




Art Shop Powerful Adhoc Reporting




A REST interface (built with Web API) allows external clients to access the Art Shop via a well-designed web service.

As you can see, the application is comprehensive, but the solution is remarkably compact and simple. It has only 4 projects of which 2 are optional (the REST and REST test projects). Here is an overview of the Art Shop solution in Visual Studio.


Art Shop Solution



The first project, Art.Web, contains the Presentation layer. The second project, Art.Domain, holds the remainder of the application including the Service, Business, and Data Access layers. A perfect, yet simple structure to work with.


Next we'll explore the Spark platform, which was used to construct the Art Shop.

SparkTM


9.   SparkTM 4.5  Platform

We are super excited about the addition of Spark to our latest release of the Design Pattern Framework. Spark was developed by DoFactory and it is a light-weight, rapid application development (RAD) platform that provides unparalleled productivity through some of the best patterns and practices. With Spark you will deliver quality apps on time and under budget.

Here are the basic building-blocks of this platform:


 Layers Presentation, Service, Business, and Data Access
 Patterns Repository, Unit of Work, Facade, Active Record, MVC, DTO, and CQRS
 Practices Convention over Configuration and YAGNI
 Libraries Automapper, Json.NET, Bootstrap, JavaScript + jQuery, and History.js


Layers
Applications built with Spark have 4 layers:
  - The Presentation layer provides the UI (user interface) and the user experience
  - The Service layer offers a simple query and service interface for the UI code
  - The Business layer offers the business objects with business rules, and
  - The Data Access layer provides fast data access to and from the database
Rest assured, the layering model is explained in great detail in the documentation.

Patterns
Spark uses a limited set of patterns from 3 major patterns categories: Gang of Four, Enterprise, and Model-View. A very important pattern in Spark is Active Record. This pattern essentially merges the data model and the object model into one. Having to remember only a single model greatly simplifies and accelerates development.

The table above lists the key patterns in Spark. In case you're not familiar: DTO = Data Transfer Object and CQRS = Command Query Request System. Again, all design patterns and their use are explained in the documentation.

Best Practices
A core paradigm in Spark is convention over configuration. The Spark platform follows some simple conventions which greatly increases developer's productivity. All best practices used in Spark share a common desire for simplicity and productivity.

The table above lists the key practices in Spark. In case you're not familiar: YAGNI = You aint gonna need it, meaning only develop what is absolutely necessary; nothing more and nothing less.

Libraries
Spark uses a limited set of open-source tools and libraries which includes both .NET and JavaScript libraries. Together they accelerate development and enhance the user experience.


Building apps with SparkTM is quick and easy!

Spark is pervasive. This is clear from the diagram below which depicts the scope of Spark throughout the application stack (Spark is represented by the light-blue parts):

With so much code and infrastructure in place, no wonder that productivity is high.

The white areas in the diagram are the extension points where you add your application-specific code. MVC is mostly white, so this is where most of the development will take place. Guess what, this is the perfect place!  Your applications are unique and the presentation tier is where you express this uniqueness by building unique UIs and user experiences -- as opposed to the more humdrum service, business, and data layers.


Spark is an exciting, light-weight, pattern-based technology that will greatly accelerate and enhance your .NET projects. Try it for yourself. Once you experience the benefits you won't go back!


Benefits of SparkTM 4.5

 Accelerate your projects, your apps, and your career

Spark captures many years of pattern based .NET development experience and makes it available as a powerful RAD platform. It allows developers to create applications quickly and easily. Get your own copy of the Design Pattern Framework 4.5 today and accelerate your projects, your applications, and your career.

 Works for all .NET UI platforms. And beyond

Spark is not limited to MVC. The bottom three layers in Spark support all .NET platforms: ASP.NET MVC, ASP.NET Web Forms, WPF, and Windows Forms.

In fact, it goes beyond .NET. By exposing a REST interface non-Microsoft platforms can interact with your apps as well. This includes mobile devices such as IPhone, IPad, and Android and many others (the green boxes below).

By the way, Spark offers great support for building REST interfaces. The sky is the limit.

 You're always in control

Applying Spark to your applications requires that you follow some simple conventions and patterns. However, these are flexible enough to let you refine or tweak the code in each of the layers with specially designed extension points (implemented as partial classes, partial methods, and virtual methods). Spark is flexible and leaves you always in control.

 You can focus on what is really important

Spark takes care of the more mundane tasks, which allows you to focus on what is really important: creating wonderful apps with a unique front-end and user experience. The UI is where you really want to spend most of your development time because this is what sets your apps apart from others.

 Deliver applications on time and under budget

The Spark platform takes responsibility for large parts of your applications. This will give you a huge head start allowing you to easily meet (or beat) all deadlines and deliver your apps on time and under budget. No more deadlines -- imagine that!

 Struggling with impedance mismatch? Consider it solved!

The Active Record pattern plays an crucial role in Spark. This pattern essentially merges the object model and the data model into one. As a developer this is great because you only need to keep track of a single model rather than two very different models. What's more, you don't have to worry about the dreaded impedance mismatch anymore.

 Spark is a MicroORM. And more

Interest in MicroORMs (Object Relational Mappers) has grown significantly over the last couple years. Well known MicroORMs include Dapper, Massive, and PetaPoco. Spark is a MicroORM also, but without the limitations of the others.

For example, Spark data queries return type-safe business objects rather than dynamic .NET objects (which is what Massive does). Dynamic objects are more difficult to work with because they don't support Intellisense and may cause unexpected runtime errors. Furthermore, Spark does not require that you write full length SQL statements as in Dapper and PetaPoco. In Spark you provide small 'where' and 'orderby' snippets giving you the full flexibility of SQL but without the overhead of writing lengthy SQL statements.

Indeed, Spark is a MicroORM, but that is only part of the story. Spark also provides guidance, patterns, conventions, and code for the entire applications stack.

  No JOINs! Simple and super fast data access

Applications in Spark rarely require SQL JOINs. If this sounds unbelievable, the Art Shop reference application does not use a single JOIN in the store! This is made possible by a combination of 1) data model conventions, 2) data caching, and 3) automatic updates of aggregate column values. Data access in Spark is simple and extremely fast! There are few apps that can make that claim.

Just to be clear, the Art Shop admin area does use JOINs. This is where non-transactional analytics and reporting queries are issued, so this is to be expected.



 PRO  Design Pattern Framework 4.5

PRO Design Pattern Framework 4.5 With this release we also offer a new edition of the Design Pattern Framework called PRO Design Pattern Framework 4.5. It comes with a T4 code-generator that automatically generates three out of four application layers: Service, Business, and Data Access -- as well as a large part of the REST interface.

With most of the mundane and repetitive code out of the way, you can immediately focus on the UI and user experience. The PRO framework allows you to develop .NET applications up to
4 times faster!

Before purchasing the PRO package, we strongly recommend that you first explore and evaluate the standard Design Patterns Framework 4.5 with Spark. There is no risk because if you decide to upgrade we've already discounted the standard price from the PRO purchase price. To learn more about the PRO version click here.

Bonus 2: Head First Design Patterns


If you have been following what is going on in the world of design patterns then you know that the Head First Design Patterns book is one of the more popular pattern books. It is one of those rare gems that has the ability to make something as complex as design patterns, easy and fun to learn.


Unfortunately, this book is targeted at Java developers and comes with code samples in Java. Indeed, Java is similar to C#  but the samples use Java types and Java packages which makes the code all but irrelevant for .NET. Examples are: Swing, Applets, Observer/Observable types, Java I/O classes, and Java RMI (remote method invocation). It's hard to study these patterns and be concerned about subtle, and not so subtle, language and platform differences.


As an extra bonus, the Design Pattern Framework includes a complete set of Head First Design Patterns in (C# and/or VB). You'll get a total of 46 Head First Design Pattern projects nicely packaged in an easy to use .NET solution. Simply create a shortcut on your desktop, double click, and all source code projects are available at your fingertips.


Head First Design Patterns for .NET





The Head First book itself does not reference the Java code samples which makes it hard to link the samples back to the appropriate pages in the book.

This is why we are including a reference document that relates each .NET project back to the appropriate page number where the topic of the pattern begins. In addition, this document also highlights the differences between Java (i.e. the book) and the .NET implementations of these patterns. So, snuggle up in your favorite chair with this book and the .NET code samples and make learning design patterns a fun experience.
