Abstract

The KLOE experiment at the Frascati phi-factory DAPHNE, designed to measure $\Re(\epsilon^\prime/\epsilon)$, began preliminary data taking in the Fall of 1999. A large database structure, which logs information coming from the DAPHNE control system and the KLOE slow control and data acquisition systems, has been developed. Data from detector monitoring, online event processing and machine operating conditions are easily accessible for online and offline analysis by means of Web tools and histogramming tools. The system allows powerful real-time data correlations which are necessary for the ongoing program of luminosity and background improvements. Data flow and handling processes are presented.
