DDBST is celebrating its 25th anniversary.

DDBST GmbH was founded in 1989. The main goal was a professional, commercially oriented development, support and further extension of data banks and calculation programs. The Dortmund Data Bank is the largest factual data bank for experimental data on pure components and mixtures and available via in-house versions, online (STN, Internet) and in printed form. The DDB currently (2015-Jan) contains 6.8 million data tuples for 46,040 components from 154,000 evaluated references. The data bank can be searched online for free (only data from the open literature are reported).
