    Alarm Reporting in River Information System
    (Managing Environmental Knowledge, 2006) Bec, Sonja; Pecar-Ilic, Jadranka; Skocir, Zoran
    This paper gives a description of the most significant parts of the development of the Alarm Reporting Subsystem of the River Information System (River IS). River IS will provide efficient waterway related data management at national level for the Croatian part of the Danube River. Our research in that area dates from the year 2000, and since 2003 is carried out within the CROatian River Information Services (CRORIS) project. In this paper, first the main functionalities of River IS are outlined, and then the alarm reporting process is described in detail. We were interested in alarms and regular status checks from buoys and floats positioned along the river and regular status checks of displays from the bridges. Provision of measurement data from the floats as well as water level data along the river was also required. For modeling of the requirements the UML Use Case diagram was used and based on it and the characteristics of chosen SVG (Scalable Vector Graphics) and Web technologies the Class diagram representing the Static Structure was developed. Along with the description of the diagrams, especially the characteristics of the alarming and SVG technologies were discussed. In the end, an example of the map interface with explained access to reports is shown.

    Object-relational Database as a Data Source for Interactive Dynamic Web Application
    (Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Pecar-Ilic, Jadranka; Ruzic, Ivica; Skocir, Zoran
    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
