Local organisations cover functional needs not provisionally or sustainably supported by national information systems by developing local applications. They cover extremely diverse realities. National organizations sometimes generalize some later on. The Court observed in the case of the family class that they do not systematically comply with national standards of design and documentation and that they can, therefore present certain risks for the integration of data in central information systems and, where appropriate, for the security of the latter. Lack of national approval of local applications can sometimes lead to risks of deviations from existing legislation.
