A chess data base serves chess analyses for storing games of chess, or also from chess compositions.

Portions and analyses

Most chess data bases contain many played portions, in some also of analyses are stored. They help for example with the study of openings or also during the preparation on the next opponents, if the data base contains portions of this opponent. In addition opening libraries as well as dynamic weighing functions for chess programs can be generated from the volume of data.

ChessBase

1985 developed the Bonn physics student Matthias the first chess data base for the "“Atari ST"” computer, accompanied with interest and advice of the chess world champion at that time Garri Kasparow. Together with that Hamburg chess journalist Frederic Friedel it created the company ChessBase and published 1987 ChessBase 1.0. They are to today world market leaders in this market segment.

Chess Assistant

A further common data base program is the Russian Chess Assistant. Both data bases are delivered in the meantime with scarcely 3 million portions. They are continuously supplemented. One can insert also own portion collections.

Alternative one

Free alternatives are the chess data base and Scid.

Aid

Integrated and external chess programs help during the analysis and evaluation of positions.

Chess composition

In a chess data base also chess compositions can be stored and classified. Often material for such data bases was already gathered and collected before the computer era.

The most extensive study collection administers Harold van the Heijden. In version 3 (2005) it contains of 67,691 studies. It is very far progressed regarding the degree of the completeness. In it partial collections of several collecting tanks are integrated. It is an example of a high measure of co-operation of many participants.

Over 200.000 problems at present the chess data base contains WinChloe of the Frenchman Christian Poisson (conditions April 2006) of all kind. The data base can be acquired with authors and can over Internet be updated. The release program had automatic topic recognition, any kinds of board and figure types are graphically representable.

A further example of good co-operation with the completion of collections is the PDB server, which can be queried by Internet. On it the auxiliary matte collection was decentralized seized by John Niemann by several chess friends. Further partial collections from other ranges of the chess composition were added. However it is based not on a chess data base, but on on a general data base with the possibility of a reduced SQL inquiry for everyone. Their Hauptproblem is the unreliability of the data (doublets, inaccuracies,"…). However everyone can contribute by comments at the improvement of the information. The actual problem exists in the continuous processing of the detailed comments, which is done so far via particulars by manual work partially.

Further collections (orthodox miniatures, Selbstmatts,"…) exist at present only in the hands of individuals. It exists there no individual accesses from the outside. But the data contained in them might be more reliable. Also in them results already different collecting tank (like Albert Heinrich kneel, later taken over from Peter kneel) are integrated.

A typical example for this is designated the not yet completely seized Albrecht collection, after the composer Hermann Albrecht. This began 1933 to collect and classify on record sheets. When its dying 1982 this work covered about 80,000 problems. Udo Degener transferred this collection to EDP systems. General accesses is still pending from the outside.
