In existing implementations of distributed databases, when computing a join using the semi-join algorithm, is it assumed that the possible values of the joining attribute are known at both sites? In other words, can bit strings be sent rather than actual attribute values? Thanks. ross%goanna.oz@uunet.uu.net
