ASP.NET 4.5 Architecture

Request Processing

IIS gets the request

Looks up a script map extension and maps to aspnet_isapi.dll

Code hits the worker process (aspnet_wp.exe in IIS5 or w3wp.exe in IIS6)

.NET runtime is loaded

IsapiRuntime.ProcessRequest() called by non-managed code

IsapiWorkerRequest created once per request

HttpRuntime.ProcessRequest() called with Worker Request

HttpContext Object created by passing Worker Request as input

HttpApplication.GetApplicationInstance() called with Context to retrieve instance from pool

HttpApplication.Init() called to start pipeline event sequence and hook up modules and handlers

HttpApplicaton.ProcessRequest called to start processing

Pipeline events fire

Handlers are called and ProcessRequest method is fired

Control returns to pipeline and post request events fire

SQL : Sql Query Execution Order

Most programming languages executes set of statements from Top to Bottom but SQL Server executes set of statements in a logical order which is uniquely decides by the SQL Server in a predefined order known as Logical Query processing phase.

Introduction

When we are developing an application our concern mostly related to the code optimization which enhances the performance of application. When we are talking about an application it has broadly divided into two part one is the our code written in any programming language and other is the code written in database which executes at database level and return the results to our application.
In real world most application facing the performance issue which can be improved by code optimization. Here we will talk about the SQL query optimization.Most programming languages executes set of statements from Top to Bottom but SQL Server executes set of statements in a logical order which is uniquely decides by the SQL Server in a predefined order known as Logical Query processing phase.

Backbone.js – Basic Understanding of Model

Backbone.js Models

When we talk about MVC pattern, Model becomes very important part of this. It is the Model which contains application data. The authors of backbone.js have quite a clear definition of what they believe the model represents in Backbone.js.

Models are the heart of any JavaScript application, containing the interactive data as well as a large part of the logic surrounding it: conversions, validations, computed properties, and access control.

What we have till now-

In my last post Backbone.js, We have created a HTML page named main.html in which we had included the required script files. Let's create a new js file main.js and includes this file in our main.html page.

<HTML>
 <Head>
  <title>Backbone js Tutorial</title>
 </Head>
 <Body>

  <script src="scripts/underscore-min.js"></script>
  <script src="scripts/jquery-1.11.3.min.js"></script>
  <script src="scripts/backbone-min.js"></script>
  <script src="scripts/main.js"></script>
 </Body>
</HTML>

What is Backbone.js ?

Backkbone.js is a JavaScript library that let us create Single-Page Applications (SPAs) in structured manner. Backbone.js is based on Model-View-Controller (MVC) design pattern. It is suitable for creating Single-Page Applications (SPAs) using RESTful services for persisting data.

Components in Backbone.js-

Unlike traditional MVC which have three components, Backbone has following main components-
