After an enjoyable time at the SORT conference in 2011 I was invited to come back to SLC to present at the RootsTech Genealogy conference. The two hardest data types to model are e-commerce and genealogy. There really just isn’t any good way to do it in a relational database. MongoDB is the answer Genealogy developers have been looking for for a very long time. A flexible schema that allows adhoc searching, horizontal scale and full data integrity.
