Implementation of the Intranet
An Intranet must be designed in accordance with the needs of 
the enterprise or of the organization (at the level of the services to be 
implemented). The Intranet must therefore not only be designed by the 
computer engineers of the enterprise, but within the scope of a project 
which takes into account the needs of all the parties interacting with the 
company.
Insofar as physical setup is concerned, it is sufficient to set up a web 
server (for example a machine running under Linux with the Apache web 
server and the database server MySQL or rather a server under Windows 
with the web server Microsoft Internet Information Server). It is then 
sufficient to configure a domain name for the server.
Extranet
An extranet is an extension of the information system of the 
company to its partners located outside of the network. Access to the 
extranet must be secured to the extent that the same provides access to 
the information system for persons located outside of the enterprise. This 
might involve simple authentication (authentication via user name and 
password) or strong authentication (authentication via a certificate). 
It is recommended to use HTTPS for all web pages that are 
consulted from the outside to secure the transport of HTTP queries and 
answers and to prevent, in particular, the open transfer of the password on 
the network. An extranet is therefore neither an Intranet nor an Internet 
site. It is rather a supplementary system providing, for example, the clients

Groupware 
The term “Groupware” refers to the methods and software tools 
which allow users to carry out joint work across networks. The term 
GroupWare therefore refers to miscellaneous and varied applications 
which contribute to one and the same goal: allowing users that are 
geographically apart to work in a team. 
Teamwork can be conducted through sharing information or 
rather creating and exchanging computerized data. In most cases, 
groupware refers to messaging tools (whether instantaneous or not) as 
well as miscellaneous applications such as:
➢ Shared agenda
➢ Shared document workspace
➢ Information exchange tools (electronic forums)
➢ Contact management tool
➢ Workflow tools
➢ Electronic conferencing (videoconferencing, chat, etc.)
