12. Developing Map Databases: Problems and Solutions

This article is an introduction to a several-year long development focusing on the building of a digital map database, named EDIT (Elek I (2010) Nagyméretű térképi adatbázisok fejlesztési és működési tapasztalatai. In: Dövényi Z, Fodor I, Lovász GY, Schweitzer F, Tóth J (eds) Geográfia-2010-Pécs. Pécsi Tudományegyetem, Pécs). The theoretical background, the applied technology, the developed information system, and its perspectives will be described. The classical relation database technology and the object oriented, document based database management (Elek I, Giachetta R, Máriás ZS (2009) Egyetemi digitális térképtár fejlesztése az ELTE-n.

The system is not only a rich data source for researchers but also a virtual laboratory of the database technology where various database management systems related to GIS can also be investigated. The EDIT system has become an ordinary data source of the research and education at Eötvös Loránd University and its partners in Hungary (Elek I, Kovács B, Verebiné Fehér K (2004) Digitális térképtár az ELTE-n, Magyar Földtudományi Szakemberek VII. világtalálkozója, Hungarian Geological Society, Budapest: 80). The role of the system is of remarkable importance in the doctoral training too (Rigaux P, Scholl M, Voisard A (2002) Spatial databases with application to GIS. Morgan Kaufmann, Burlington).
