Zusammenfassung
A specialized Information system for the data of water quality monitoring for the Danube River Basin has been developed. The Information system enables efficient environmental water-related data management and its verification was performed using the data from the Environmental Programme for the Danube River Basin (EPDRB), in which we actively participated (Pečar-Ilić/Ružić 2001). This paper brings out the most significant aspects of the Object Oriented (OO) modeling of the database for the surface water quality monitoring within the EPDRB. The database was implemented in the Oracle® ORDBMS and served as a data source for the interactive dynamic Web application for temporal and spatial presentation of relevant data. The use of ORDBMS as a database server in a Web based three-tier client/server architecture, such as integrated Information system architecture, has many advantages compared to the use of relational DBMS. The main concepts influencing the increase in Web application performances have been described
