ABCData project is an online bioarchaeological database, that essentially gathers palynological and anthracological data. This relational database was built using a framework (FuelPHP), and the different interfaces and applications were all developed through computer programming, using several languages and open access libraries. In particular, we developed a paly-nological query interface associated to a SVG graphics generation tool. We tested ABCData’s functioning through the integration and the analysis of numerous palynological cores that had already been studied with a different method. This study revealed a great accordance between the two methods, and highlighted some bias and the necessity of permanently watching over of the statistic distribution of the samples
