A methods database is a structured collection and description of evaluation methods and their properties, including the tools for defining the structure and manipulating their properties. The basic modules of the digital evaluation methods are stored and organised in a methods library. Numerical models (e. g. simulation models) or interfaces for importing and exporting data and for visualising results (e. g. GeoViewer) can also be connected to methods databases. A methods database or a respective system can be part of a land information system.
The FISBo BGR methods database currently offers around 50 different evaluation options for soil-relevant issues. From a technical point of view, a ‘methods database system’ is a software system that is generally made up of the following components:
- One or more methods databases as a collection of programmes (module database) for determining characteristic values. The individual programmes are structured in the same way, are called up with a command and controlled via parameters. The methodically correct link to the database contents (e. g. profile data) is then also defined in the programming implementation of the various modules.
- A control system that controls access to the data and method application with the appropriate user interface. The tasks of the control system include defining new methods, executing the methods, providing information about methods, delivering results and access control.
- A system catalogue with documentation of the methods and the user help (manual).
