Database Compression

Database compression is an operation that reorganizes contents of the database file, reducing its size.

Compression will have significant effect on the database file size if a large amount of data was deleted and the database file is therefore filled with data only partly.

There's no need to compress the database file during normal operation. A good reason for database compression is e.g. that the database backup file cannot be copied to a backup medium.

Compressing is executed by calling the cd_Compact_database API function.
