Christopher Winslett: Temporal Joins
My first thought seeing a temporal join in 2008 was, “Why is this query so complex?” The company I was at relied heavily on database queries, as it was a CRM and student success tracking system for colleges and universities. The query returned a filtered list of users and their last associated record from a second table. The hard part about the query isn’t returning the last timestamp or even performing joins, it’s returning only their last associated record from a second table.
