Abstract

We present CLOUDS, which stands for C++ Library Organizing Uncertainty in Database Systems, a tool that allows the creation of fuzzy reasoning systems over classic, nonfuzzy, relational databases. CLOUDS can be used in three flavors: CLOUDS API, a C++ API; CLOUDS-L, a compiled language; and CLOUDSQL, a fuzzy extension to SQL queries (ANSI, 1992). It was developed using the objectoriented paradigm and has an extensible architecture based on a main control system that manages different models, and runs queries and commands defined in them. As a test, it was incorporated into a geographic information system and used to analyze epidemiological data.
