Client/Server architecture

Flexibility of interventions is encouraged by focusing on thin-client systems, as the data are centralized on a single server, hence allowing for better data security software.

The client-server structure is based on the three-third or N-third principle of architecture and has proven efficient, particularly by improving the power of data processing in web-search engines for a large number of customers.

This architecture is based on technologies that have been mastered and that are more mature.
CELAD participates in various projects focused on client/server development (analysis, design, development, development, testing …)
