[comp.databases] Implementation of Semi-joins

ross@goanna.oz (Ross Wilkinson) (07/28/89)

Can anyone help?

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.
