One would expect “data scientists” to be keen on the dual scientific foundation of database management -- the relational data model (RDM) -- but they know little beyond “related tables” and, in fact, complain that more often than not data “do not fit” into them. Much of that is the result of poor education and an almost exclusive focus on software tool training. Even the analyst intent on acquiring foundation knowledge is more likely to be misled than enlightened by published information.
