Datomic is not a SQL database. You can simulate tabular data, but it is a very different beast. Datomic schemas are always EAVT. If you add an attribute, or deprecate one, there may still be values tagged to that attribute. That should be fine. That something as simple as change--a universal condition of all systems--defeats so many schema designs in SQL databases should suggest that there's something wrong with the SQL databases.
