The SDSS project will produce tens of terabytes of non-trivially related data with uncertain complexity in usage. The survey is being conducted by an international collaboration consisting of eight institutions scattered throughout the US and Japan as well as numerous individuals at other sites. The data archive must provide adequate access to all collaborating partners during the five-year survey lifetime to support: development and testing of software algorithms; quality analysis on both the raw and processed data; selection of spectroscopic targets from the photometric catalogs; and scientific analysis. Additionally, the archive will serve as the foundation for the public distribution of the final calibrated data on a timely basis. In this paper, we document how we applied Object-Oriented modeling and design to the development of data archives. In the end, based on the experience, we put Object-Orientation into perspective.
