Abstract
A relational database management system has been implemented on the Ca ltech millimeter-wave array for both real-time astronomical and engine ering data and post-processing calibration and analysis. This system p rovides high storage efficiency for the data and on-line access to dat a from multiple observing seasons. The ability to access easily the fu ll database enables more accurate calibration of the raw data and grea tly facilitates the calibration process. In this article we describe b oth the structure of the millimeter-array database and the implementat ion of a data analysis program, both of which make extensive use of Sy base, a commercial database management system with application develop ment software. This use of relational database technology in real-time astronomical data storage and calibration may serve as a prototype fo r similar systems at other observatories.
