For
convenience I have split events into various categories, such as
discipline' for individuals - which might record Court
Martials, punishment or dismissal - or milestones' for ships -
which might record launch, rebuild or loss. Operational data
will undoubtedly need to be added at a later date but is not entered
at present. Every event is tied to the date and source of data.
In
many instances, the sources differ over dates. In general
terms, I use the most convincing primary source as the master'
date. Except for obvious errors in secondary sources, I record
these alternatives on the database and, if subsequent clearer
information becomes available, it is a simple matter to change the
master' date. Information on alternative data is not
available in standard reports.
