As support for these tasks integrated environmental information systems are necessary. This paper gives an overview over some approaches which allow the development of either integrated environmental data bases or ones that can be extended and integrated at a later date. Firstly, the basic approach for integrated environmental databases is presented – the data warehouse (DW) with integrated management of geographical data – as well as alternatives: DWs with integrated application for data collection, with external management of geographical data, and with specific applications for mass data such as measured values. Secondly, some aspects of data modelling with respect to content and techniques are pointed out; in detail these are units, chemical substances, biological taxonomy, (aggregated) measured values, conventions for database schemata, object type catalogues and version management.Text/Conference Paper
