Online Tutorial
Application
(Project on REST-ful WCF)
Prem Vemosh Kumar K S
DO Final Project – CSE 775
Agenda

Create a web application that can serve as a tutorial application.

Service operations to create, manage and delete the user profile information.

Documents and other content will available to the user based on their
subscription.

Service operations to add and download the tutorials into the system.

Usage of content management system to handle the documents uploaded.
Technologies Used

RESTful WCF (Windows Communication Foundation) will be used to create the
services and its operations.

C# and ASP. NET will be used to create the online web application that will
serve as the client to the services.

MS SQL Server will be used as the database management system that stores
and handles the user information.

MS SharePoint will be used to maintain the content uploaded through the
application which can be documents, images or other approved content
formats.
Representational State Transfer (REST)

Representational State Transfer (REST) is a software architecture style
consisting of guidelines and best practices for creating scalable web services.

Some Features and Constraints;
•
Resources Based - Everything is a resource and it is identified through URI.
•
Representations - How resources are manipulated. Typically XML or JSON is used.
•
Methods - Operations are done on these resources through HTTP Methods like Post,
Get, etc.
•
Uniform Interface - Defines the interface between client and server.
•
Uniform Interface = Resource’s URI + Methods + Representation.
•
Stateless - Each message will be self descriptive and independent.
Windows Communication
Foundation(WCF)

It was first introduced with .NET Framework 3.0.

WCF is a Microsoft platform for building interoperable and distributed
applications.

Summary all of the different distributed programming infrastructures offered
by Microsoft.
Java Web application - (HTTP protocol/XML Format) – End Point 1 - WCF
Windows application - (TCP Protocol/ Binary Format) - End Point 2 - WCF

Another major difference is that Web Services Use XmlSerializer. But WCF
Uses DataContractSerializer which is better in Performance as compared to
XmlSerializer.

Service Interface Definition:
namespace ServiceExample
{
[ServiceContract]
Public Interface IWcfExample
{
[OperationContract]
ReturnValue ServiceOperationOne(param1, param2);
[OperationContract]
ReturnValue ServiceOperationTwo(param1, param2);
}
}
A class should use the interface and define the operations needed. End point configurations has
to be done in the configuration file.
Simple Service Call:
using (HTTPResponseObject Obj = new HTTPClient().Post("Service Operation URI Entered Here",
HttpContentExtentions.CreateDataContract(RequestEntity)))
{
if(Obj.StatusCode.Equals(System.Net.HttpStatusCode.OK))
{
ResponseEntity = Obj.Content.ReadAsDataContract<Response>();
}
}
Implementation Plan

Services for Registration, Login, Edit and Delete profiles will be created.
These services will help in managing the user profile information and their
subscription for tutorials.

Only the content under the topics which the user have subscribed for, will be
available for download or view.

Services for uploading and downloading the content from the content
management system will be created. MS SharePoint will be managed through
these services for accessing the content through the application.

Implemented services will be hosted in ISS.
Microsoft SharePoint

SharePoint is a web application framework and platform developed by
Microsoft.

SharePoint offers a set of tools that can be used to provide intranet portals,
document and file management, collaboration, workflow capabilities and
social networks.

One of its features called Enterprise Content and Document Management will
be used in this project.

A content library will be created to manage the contents uploaded through
the application.

Either the concept of Content types or tags will be used to categories the
content available based on the topics defined in the application.
Microsoft ASP .NET and SQL Server

ASP.NET is a development framework for building web pages and web sites
with HTML, CSS, JavaScript and server scripting.

ASP.NET supports three different development models:
Web Pages, MVC (Model View Controller), and Web Forms:

I will be using Web Forms model to develop my application.

Microsoft SQL Server is a relational database management system developed
by Microsoft. As a database, it is a software product whose primary function is
to store and retrieve data as requested by other software applications,
running in the same or different machine across the network.
