Database analysis

A database report tool is included:

   dbreport filename

analyses the integrity of the database by checking numbers of attribute values for each entry, and provides coverage statistics for each attribute.

Example:

   dbreport sfb.lex

NOTE: In order to avoid creating a wrong impression about the
      amount of information contributed by the individual
      projects, the following important point should be
      borne in mind:
      The percentages denote only the coverage of entries.
      They say nothing about the amount of information in the
      individual subdatabases. For this the subdatabase
      reports (see Appendix) must be consulted.
