We review the architectural design and implementation of the Euclid Archive System (EAS) which is in the core of the Euclid Science Ground System (SGS) and represents a new generation of data-centric scientific information systems. It will handle up to one hundred PBs of mission data in a heterogeneous storage environment and will allow intensive access both to the data and metadata produced during the mission. This paper makes a particular emphasis on the access to science-ready products and interfaces which will be provided for the end-user.
