I already have a number of databases, including one of about 2 million games
all of players at or over 2200 ELO. The quality of this database is good,
but I want to be able to use a database in the Training > Openings feature.
When I load any database of this number of games into this feature the
indicator tells me it will take over 300 hours to load.
This is why I was mistaken about what an opening database is. Given that it
takes so long I made a perhaps natural assumption that an opening database
must be different to a set of full games. I realise now that this was very
wrong.

I have used the ECO browser but I don't think this can be used in the same
way as the Training > Openings feature does.
