The aim of the project is to identify critical processes and systems between entities, and within entities where necessary, that involve the exchange of information on irregularities in European funds; capture interoperability models between systems at the functional (data and flows) and technical (integration service techniques, middleware, traceability control, structure formats) levels; assess the adequacy of the integration architecture between systems and propose changes with a view to improving the management of data on irregularities and fraud involving European funds.
