I always considered "nuclear winter" to be a hoax and scientifically incorrect—and have said so in my Nightline debate with Carl Sagan. The data from the Kuwait oil fires support this view. Actually, nuclear explosions would create a strong greenhouse effect and cause warming rather than cooling. Let's hope we never have to find out.
A database is an organized collection of data. The data are typically organized to model relevant aspects of reality in a way that supports processes requiring this information. For example, modeling the availability of rooms in hotels in a way that supports finding a hotel with vacancies.
