Exploitation of statistical tables: conceptual interaction with epidemiologic data.

Health-care applications need flexible data and interaction models capable of dealing with data of different natures coming from different sources. These applications are usually devoted to diverse user groups, often casual or novice. The user interface must help the user to understand the database information content in his or her querying process. The authors synthetically describe FLN, a system featuring an integrated interaction with epidemiologic data. In an integrated model the statistical aspects of data (macro data) are represented, together with the intensional and extensional views of the variables involved in statistical tables.
