The Lake Database (SeeDaBa) has been developed as modern web application by ENDA. It is used by the German UBA to collect the measurement values from lake samples from different depths provided by the federal states authorities and to conflate then in one application. The core data, concentrations and other parameters can be aggregated, queried and filtered, exported in standard formats and visualised. The reports for the EEA can be automatically generated to fulfill the respective reporting obligations.
The application core (role and priviledge management / login, form and table views for thematic data, list selection dialogues and navigation) has been redeveloped. The front-end is developed in Objective-J, a superset of JavaScript, and is running in the browser. This keeps load from the server.
SeeDaBa has a journal that provides unlimited UNDO, import functions that support different data formats to cope with the data from federal authorities and a flexible, powerful yet convenient query tool with result download. Special emphasis was put on graphical evaluation functions, that provide the user with annual concentration series, display of threshold value violations, visualisation of lake specific properties and core data overview.
The lake database has a complete object history by means of date-framed definition periods.
