If it's SLC, then they will want to have final overwrite on the existing base. If it's the Ward/Stake, then the task falls to the clerks. Some one needs to own the data at some point in the exercise. Databases and locking merely enforce the policy.
My experience with the financial piece of MLS leads me to believe that SLC is the owner of the gold data, not the stake - and therefore they will overwrite to bring my copy in line with theirs. If it's different, then yes, more work is required at the application level to resolve this. ...Paul > > _______________________________________________ > Ldsoss mailing list > [email protected] > http://lists.ldsoss.org/mailman/listinfo/ldsoss > > > --No virus found in this incoming message. > Checked by AVG Free Edition. > Version: 7.5.430 / Virus Database: 268.14.14/547 - Release Date: > 11/22/2006 5:41 PM > > _______________________________________________ Ldsoss mailing list [email protected] http://lists.ldsoss.org/mailman/listinfo/ldsoss
