Fact file Beilstein database

Four years later the first version of the system was complete. It was immediately integrated into the production scheme of the Beilstein Handbook and the Beilstein database. The Beilstein database was extended names generated by the system became a normal searchable data field in the Beilstein file offered by both DIALOG and STN information networks. Later, they also became fully searchable in the CD-ROM Current Facts information service, as well as in the biggest in-house chemical database system, CrossFire, which has been offered by Beilstein since 1994. 

Fact files mostly include a great number of single fields which are non-text fields but often containing numeric, such as physical and thermodynamic data of compounds. Fact files are for instance Registry File, Beilstein and Gmelin as well as Specinfo. Some numeric databases - special kind of fact files - even allow calculations to be made, e.g. in Inorganic Crystal Structure Data. 

Search terms in the same paragraph (bibliographic databases) or in one line (fact files, e.g. Beilstein) (P). 

This description sees the elements of the database as structures linked to properties linked to references, and a chemical reactions database is included . This reflects exactly the historical development of the Beilstein Handbook, and later the Beilstein file on STN and DIALOG these collections are lists of compounds, with subsections on property type, linked to sub-subsections of reference lists. But the CrossFire implementation is much more than this. It has a different data orientation, and can justly be regarded as a new implementation, in fact a... 

During the 1970s and 1980s, VINITI and ZIC built a structural datafile of 3.3 million organic and organometallic compounds and facts covering the worldwide literature from the period 1975-1991. This database is similar to the Chemical Abstracts (USA) and Beilstein (Germany) structural databases. The information on the preparation of the compounds was transformed into 2.5 million reaction equations by the ZIC Institute. This file has been transformed into a commercial electronic reaction database by InfoChem, and is called the InfoChem Reaction Database.
