And google translated the main text into:

BAAN is the customer-server evolution of the software package TRITON used with the stores since 1995. This version was put in production in May 1999. It offers, in addition to certain additional functionalities a graphic user interface. Here you can downloader the graphic version (unzip and executer the setup program). We benefitted from the installation of this new version to integrate certain additional functionalities (invitations to tender, estimate of sale, etc.) in order to stick to more close to the needs expressed by the users. We also set up a new interface with Siriac and CFU allowing a greater internal autonomy and an increased automation of the mechanisms of transfer of data inter-applications. The integration of the stores with the other administrative applications: SIRIAC for the purchases part, ORIAC for accountancy, EDH for the requests users and the catalogue is thus reinforced. For further information, visit our bonds!

Hope this helps,
