"This paper describes the development of software for a user workstation for the analysis of acid rain data. The station is implemented for an IBM Personal Computer Model XT or AT. The workstation is used to build a local database abstracted by the user from various environmental data collections concerned with lake acidification. The query language is based on a pictorial representation of the geographical area under analysis, arranged in an hierarchical-fashion, to allow the user to examine the database with a geographical perspective. The data are organized in a flexible fashion for the user, and made available for browsing and simple statistics in a spreadsheet fashion.The aim of the station is to remove the programming requirement from the user, and to allow data management using only the menus, schema names, and user defined functions. The utility of automatic reasoning systems to support the workstation is also under investigation"--Abstract. Includes abstract in English and French. gccst Acid rain gccst Software Swayne, David A.
