Object-oriented modeling and design for Sloan Digital Sky Survey retained data

摘要

The SDSS project will produce tens of terabytes of data with nonionships among them and with uncertain complexity in their usage. 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 basis for the public distribution of the final calibrated data on a timely basis. In this paper, we document how we applied Object-Oriented modeling design to the development of data archives. In the end, based on the experiences, we put Object-Orientation into proper perspective.
