Mike,

I've been spending quite a bit of time in the Books on-line. I'm trying to decide which is the best replication strategy for our compnay. According to the documentation, snapshot replication sends all the data to the subscriber. Does that mean the entire table is sent, or just those rows since the last snapshot?
