Gestion documentaire


This company, specialized in publishing contemporary furniture and vintage fixtures contacted us to obtain a quotation.
After a discussion with the manager of the gallery, we came to the conclusion that instead of developing a new independent software for their publishing business, it was preferable to unify all of their systems, which consisted of the following :

Two File Maker databases ;
Numerous Excel files ;
Two MySQL management databases ;
A SQL database for the website.

The information was re-entered and exchanged via email.

After our audit, the customer decided to entrust us the complete overhaul of its information system.
This project integrates interesting technical requirements :

Connection of more than 15 customers in ADSL which forced us to develop a particularly optimized code in order to maintain acceptable performances ;
Many image management with visualization in SVG images with the command "SVG_New_embedded_image" and a great interactivity with these images ;
A document management ;
A analyzer .eml file (archive email) ;
Imports of Excel files (direct reading using PHP) ;
