> Sure, your ORM-like framework can define basics like primary keys and maybe uniqueness constraints, but can it define partitioning schemes, compression methods or more advanced constraints? In Prolog you'd just handle those as metapredicates. There are a million different ways to skin the cat there. For example on partitioning schemes: :- vertical_partition(profile/4, [ core(1, 2), % UserID, Username -> stored in primary memory metadata(1, 3, 4) % UserID, Bio, Preferences -> stored in cold storage ]).
