It is basically correct. Your diagram could be extended by indicating that columns consist of name, value, timestamp and that super columns have names and that a column family consists exclusively of columns or super columns (never both). I might switch Row and ColumnFamily in the hierarchy too since the rows live in column families and not necessarily in the keyspace. The API masks this detail away though, by allowing you to supply a single keyspace and row key and then operations that span column families. So maybe that is more of an interpretation that depends on which side of the client you spend most of your time. Gary.
