Day 7 - First Mappings

The first mappings have been specified.

I've spent almost all day with the target team and the source teams, one from the main system and another from a secondary system.
It was a productive day, since we were able to map over 90% of both systems, that will migrate into the same target specification. The doubts and problems detected will be easily solved.

As expected, some cleaning will be performed by the trasformation rules. For instance, in some circumstances, the honorific title will have to be automatically inferred from a free form text field.
It will also be necessary to perform duplicate detection and entity fusion before executing the migration.

None of these seems really problematic at this time.
