building web apps with asp.net mvc and nosql
DESCRIPTION
This talk guides you through building modern web applications using ASP.NET MVC and MongoDB, one of the most popular NoSQL databases. You will learn some best practices for getting started with MVC. We’ll cover building rich-forms to accept user input. And if time permits, we might even add some client-side techniques using jQuery and MVC. All of this will be built upon the powerful non-relational database MongoDB. We will discuss the origins of the so-called NoSQL movement and why you might choose a non-relational database over SQL Server. You’ll also see our data access layer will be built using LINQ to MongoDB. Of course, you won’t be in for a night of PowerPoint. This talk is a series of interactive demos using Visual Studio 11, Windows 8, and C#.TRANSCRIPT

What is NoSQL?
The NoSQL movement is about re-evaluating the constraints and scalability of data storage systems in the light of the way modern web applications generate and consume data.

Why NoSQL?
Axiom: A proposition whose truth is so evident that no reasoning or demonstration can make it plainer.
DEVELOPMENTOR
Starting from an RDBMS is virtually an axiom of software development.
When was the last time you consciously evaluated alternatives to an RDBMS?
Why NoSQL?
DEVELOPMENTOR
You can keep your ‘object / relational impedance mismatch’, thank you very much!
MongoDB: A Powerful NoSQL Database
Combining the best features of document databases, key-values stores, and RDBMS.

Find several provider libraries on NuGet, including the Official 10Gen C# driver.
Demo - Part 1: Amazoon Needs a Data Layer
Time to upgrade Amazoon: Amazoon needs to be able to do basic queries and inserts / updates.

Demo - Part 2: Forms, Model Binding, and HTML Helpers
"Pure" HTML forms are valid but not optimal in MVC. Make use of @Html extensions. Html.BeginForm(), Html.TextBoxFor(), etc. Usually, this is far easier with Model Binding.

Demo - Part 2: Forms, Model Binding, and HTML Helpers
Time to upgrade Amazoon: Amazoon needs an admin section where we can create categories and books.

Demo - Part 2: Forms, Model Binding, and HTML Helpers
Well, that mostly worked. But it was clunky on several levels. * ViewBag is untyped and non-discoverable* Many parameters "capture" the form values* What about validation?
DEVELOPMENTOR
Demo - Part 3: View Models and Validation
Now that we got the site working with the new features, let's clean it up. * View Models (Model Binding at the next level)* Validation (is easier with View Models)

Demo - Part 4: Adding Real Usability with Client-Side Code
Time to upgrade Amazoon (again): Comments and discussions around books. These are already in place, but the full-page refresh is not usable on these potentially large pages.

Fully Client-Side MVC Applications
MVC 4 introduces the concept of Single-Page Applications (think gmail). These combine many technologies: * MVC and ASP.NET Web API* Knockout.js* Upshot.js* HTML5

Scaling-Out is Easier With NoSQL
So you say it's fast, eh? What do you mean by fast?

Conclusion (MVC)
Just some of the features we've explored in MVC:
* HTML Helpers* Model Binding* Unobtrusive Validation* Unified Client and Server Validation* View Models* JavaScript-Friendly Environment* Single-Page Applications (MVC 4)

Conclusion (NoSQL)
DEVELOPMENTOR
Just some of the features we've explored in NoSQL:
* Your database is a choice you make for each project* NoSQL => Non-relational* Strongly supports horizontal scale-out* LINQ works great
