Software Tools

Since the start of the DDB in 1973, a large number of software tools have been developed to search, retrieve, export, visualize and regress the data. Later these programs were extended to cover further applications like e.g. process synthesis. At the same time, data and parameter communication with other software products was enhanced. Today it is even possible to use the thermodynamic calculation engines of Aspen Plus®, UniSim Design® , Simulis Thermodynamics® or Pro/II® from inside the DDB.

All programs have been integrated under the MS-Windows graphical user interface and can be easily used even without studying the manuals.

The following table compiles most of the major parts. Detailed information can be found on the separate linked pages.
