Single-SignOn Intranet Portal On DotNetNuke

Client’s current system included a share point portal that
caters to their current needs but was not attractive enough and
was also costly. Client required a DNN portal that would be a
single point of access for all client users to access their
applications.
The DNN portal should be attractive, intuitive and should have
an appealing design so that the end users use it on a day to day
basis for their daily activities
Client Requirements

A portal solution that would be used on a daily basis with an
attractive look, user friendly design and should be cost
effective too.
Portal should have different modules controlled by access
sites given to the user groups.
Users should be able to sign in with their AD credentials.
Third party integration with features that enable users to login
without carrying their credentials.
The portal should carry the credentials into the modules.
Tech savvy users are not required to use the system.
Project Scope

User friendly controls lke rich text editors and form fields
should be provided in order to manage system and content.
Easy update and maintenance should be made available and
any asp.net developer should be able to do it.
Project Scope

Developing a portal with all current features and including
those with exclusive focus o user’s day to day activities.
Using a robust framework so that the the portal functions
smoothly even when accessed by a number of users
simultaneously.
SAP and other third party applications integration with single
sign on facilities.
Load balance must be maintained when various features are
simultaneously executed.
Web usability principles to be incorporated while developing
and designing several features for improving user experience
User privacy and safeguarding user data.

Taking into account the enormous nature of the portal and the
numerous features, the following development approach was
used
High level coding standards were used for managing the
backup data volume.
DNN (DotNetNuke) was used for this portal considering the
cost factor and allowing the client to manage the portal
content.
A complete site overhaul was done and an intuitive dashboard
was designed to attract end users and a clear visibility was
given to the important areas.
Planning

As DNN uses a three tier development approach, the same
was used for the project.
Planning

Architecture
A three tier development approach was used
Business Access Layer (BAL) – the business logics,
validations related to data.
Data Access Layer (DAL) – contains MSSQL Server
Database, Tables, Stored Procedures and so on. It also helps
the business layer to connect to the data and perform actions
such as insert, delete, update etc.
Presentation Layer (PL) – contains .asp or html where data
is presented to the user and inputs are taken from the user

Architecture

Architecture
Presentation layer can only talk to the business layer. It has
no connection to the data access layer.
Presentation layer Skills: HTML, CSS, JavaScript and UI
design.
Business Layer Skills: a programming language so that
business rules can be processed by a computer.
Data Access Layer Skills: SQL skills in the form of Data
Definition Language (DDL) and Data Manipulation Language
(DML), plus database design.

Architecture
The cycle of requests and their associated responses can be shown
in the form of a simple diagram

Advantages of a three tier
architecture are:
Flexibility : 3 tier architecture separates the business logic
and the presentation logic and makes the application more
flexible.
Maintainability: Changes in one layer of this architecture has
no effect on the other layers. Also different layers require
different skills.
Reusability: Reusable components are easy to maintain
because the application is separated into different layers.
Scalability: Application components are distributed across
various layers making the application more scalable.
Reliability: 3 tier architecture if deployed on various servers
makes the system more reliable due to redundancy

Development Highlights
Development was quick and efficient using DNN. The basic
functions ran flawlessly as DNN provided all the base
modules which were easy to deploy.
The system was capable of handling all data with ease of
access for everyone.
With a good initial analysis and planning, a well designed
system was set up with all the modules integrated into it along
with the control over user access.
Web usability guidelines were strictly followed and the
interface was made user friendly with the use of AJAX, CSS
and HTML controls. The site was developed and fully
functional within a span of 6 months.

Development Highlights
Legacy asp.net systems were integrated with DNN.
The portal was made responsive and it worked on tablets and
mobile phones as well.
