Per the "Database Design" manual:
"One LOB subtable is required for each column in a base table defined with a BLOB or CLOB data type."
"Each LOB is stored in 64 Kbyte sections in a subtable, except for the row that stores the last section. This means that for any
LOB greater than 64 Kbytes, there is not a 1:1 equivalence between the number of base table rows and the number of LOB subtable rows supporting
those base table rows."
