Le système d’information du programme 'Archéologie du Bassin parisien'. Entre SIG et SGBD, vers un applicatif Open Source adapté

One of the goals of the research program ‘Archaeology of the Paris Basin’ has been to establish an Archaeological Information System, i.e., a meta-database of the archaeological sites studied in the geographic area of the program, from the Paleolithic to modern days, in order to produce thematic maps using appropriate software. This paper aims to present this meta-database, but also to consider the technical constrains and the methodological choices involved in its implementation. The development of the query interface of this database repre¬sented an opportunity to reconsider the initial geomatic approach. This application is based on Open Source technology, and is both appropriate and adapted to the objectives of the program. It proposes an original synthesis of DBMS and GIS functionalities. Its development is in line with the rereading of the discipline paradigms suggested - or imposed - by the rise of the geomatic Open Source.
