Abstract

The use of computers in environmental research presents a number of problems both to the ecologist and the systems analyst. An analysis of some of these problems led in the reported project to the development of a prototype data base system, founded on the relational concept. In this paper we discuss certain characteristics of environmental data and their use, we show how these characteristics were mapped onto requirements on the software tools, and we describe how the final system attempts to meet these requirements.
