What is a database? A database is a collection of chess games. A database is a single collection – you may have a number of separate “databases”. You talk of the “Kasparov database” or “My King's Indian database”. Databases contain the moves of games and information on the players, the tournament, result, etc. They can also contain text reports. The games may contain analysis and commentary, including videos and sound tracks, which will be displayed when you replay the games with ChessBase.
ChessBase displays these in its database window, where each database is given as an icon and can be opened with a double click. Opening a database will list the contents of that database.
All games you enter in ChessBase are saved in Databases. If you save a new game it is added to the end of the database.
There are two kinds of databases: Normal games databases and openings books. These contain openings positions, not games.
