The Herschel mission required a Science Archive able to serve data to very different users: The own Data Analysis Software (both Pipeline and Interactive Analysis), the consortia of the different instruments and the scientific community. At the same time, the KP consortia were committed to deliver to the Herschel Science Centre, the processed products corresponding to the data obtained as part of their Science Demonstration Phase and the Herschel Archive should include the capability to store and deliver them. I will explain how the current Herschel Science Archive is designed to cover all these requirements.
