The CNAV (National Old Age Insurance Fund) is a French administration that manages the basic pension of private sector employees, self-employed workers, public-law contract workers and artists-authors, as well as the supplementary pension of self-employed workers.
The project consisted of modeling and performing the processing of batches of data from multiple pension plans. The complexity of these treatments lies in the difference in the reprocessing parameters and in that of the formats of the data batches.
