The first generation databases consist of user-shared information.
While these databases are very broad in coverage, the methods they
use to accumulate data lead to vast inconsistencies and inaccuracies
in the data they provide. The second generation of database consists
of manually entered data from commercially available CDs. While they
are able to provide more accurate data that includes richer content,
their overall coverage of CDs is severely limited, leaving big holes
in CD collections.
Get Digital Data recognized all these problems with today's databases
and thus created GD3, the next generation database. Just like second
generation databases, Get Digital Data is able to create its database
manually, however, the sample range is much broader since Get Digital
has access to every CD ever printed through its CD ripping service.
