7. CONCEPTION AND REALIZATION OF THE
APPLICATION
7.1. Classification of needs of the future users
A web portal as we have said above is a site that offers a
wide range of resource, a gateway to a specific area. Thus the following
features to respect our portal we seem to be necessary: a news page, a member
area, a messaging system, links to other reference sites, a downloadable
document page and the possibility for a member to propose content.
This means that the objectives for users are clear and
precise. However, these goals can only be achieved with the completion of a
minimum of conditions.
7.1.1. Functional needs
The portal for sustainable development must therefore offer
many features to allow the apotheosis of our goals. And these features are:
· forum
The user must be able to access the different topics discussed
in the forum. It should equally be able to see the comments of website
subscribers. However, the ability to comment in the forum is determined by an
inscription on the site as well as the ability to exchange private messages
with members of the forum. Also registered members on the forum have a visible
profile page of the portal only to members. It must also be possible for these
members to check out the lists of registered members on the site.
· The suggestion to content
Anyone authenticated on the site gets the opportunity to
suggest content. This content can be as much an article, a downloadable
document, or a link to share with the users of the site.
· The consultation paper
These articles that appear year homepage can be read by all
site visitors. Although registered members can receive an e-mail alert if they
agree.
· Hyperlinks
This page of our platform should offer the ability for users
to follow links to better learn about the different areas.
· A library
This page may show downloadable documents in relation to the
portal activities.
.
7.1.2. Non-functional needs
7.1.2.1. Quality requirements
Any site that is an attractive must be coherent and
non-polluting beauty this in order to retain its members. So we must ensure the
usability of the application. So the quality criteria may be stated as
follows:
· Ergonomics:
The need to ergonomic websites has even led to the birth of a
new discipline in web design, ie its importance to our portal. The ergonomic
approach proposes to give the power back to the human being that far from being
dependent objects must instead make use. Therefore our platform has to be
comfortable, simple, and effective.
· Assistance
The user must be able to receive assistance on certain pages
such as those forms so that we ensure that the meaning of each field is clearly
understood.
7.1.2.2. Performance requirements
Achieve a proper and sober application is a good thing, but
it must at all costs be accompanied by a certain performance. Thus we propose
the following objectives:
- The platform must be very reactive, the pages must be able
to refresh automatically;
- Errors must generate understandable messages for users;
- The document catalog must contain more than a thousand
document;
- The number of simultaneous connection must be greater than
1000;
