furthermore, i feel that their is a lack of information on these
pages. although i am pretty familiair with databases and know what
joins are, what inner joins are, what left and right outer joins
are... and let's not forget natural joins btw :-)
i am unsure what full disjunctions are. i can do an educated guess
which is probably right, but... is the target audience aware?
in fact i found no information except "The full-disjunction operation
is a variation of the join operator that maximally combines tuples
from connected relations, while preserving all information in the
relations. Useful for integrating heterogeneous data sources (web
sources). BSD License."
i guess i have to download it to find more documentation?
at least, there should be an example somewhere on these pages.
