SwingStations: a web-based client tool for the Baltic environmental database ?
This paper describes the operation of a web-based computer program designed as a client program for the Baltic Environmental Database. This database contains a large collection of oceanographic data for the Baltic Sea from all Baltic countries, covering observations from 1900 to the present. A database server manages this database allowing user access via the Internet. To investigate the database, a web-based program (SwingStations) was developed. This program works as a client in client/server interaction with the database. It allows data to be selected using graphical user-friendly queries and to analyze the data in numerical and graphical forms. It is also possible to construct vertical profiles of statistics and time series (timedepth graph) of oceanographic parameters for a selected area of the Baltic Sea. SwingStations applet is written in Java using Java Foundation Classes Application Programming Interface. This interface is included in the Sun's Java Plug-in Virtual Machine that provides complete Java Compatible support for all the popular web browsers on major hardware platforms.
