Abstract

This paper describes the architecture and the functionality of the database software developed in Project Stratus, a project aimed at the development of a knowledge based system for low clouds forecasting. This read-only software is composed of a controlling module, Db, and three slave modules. Each of the slave modules handles a different type of meteorological data. Db integrates the three modules and offers a uniform view of the different data sources. This in turn allows highly flexible data access. can be accessed either interactively by the user, or within an application written in “C” or FORTRAN. High flexibility and efficiency is realized through the use of an object-oriented paradigm, cache-like mechanisms, and data compression algorithms. Db has been proved efficient not only in the Stratus knowledge based system, but also in more traditional data processing applications, such as a tephigram display program, a contouring display program, and a numerical analysis program to compute vertical motion.
