What kinds of data can ASTEROID handle?
ASTEROID is primarily designed for consumer surveys. It uses unit record data, not aggregated figures and thus preserves the full detail of the data collected. The data is transformed into a unique database format which provides very high speed access, coupled with efficient compression and almost total flexibility of analysis. This means that very large data sets can be used. ASTEROID can also handle similar databases (e.g. Human Resources databases) where the intention is to provide statistical summaries rather than to access or update individual records.
