This is what I did at Ford Motor Co., it gets messy quick.
Even when the table is a snapshot. Nothing like a big hierarchical
table with 400 columns. *evil grin*

Nice. This could be the beginnings of a
HDBMS/RDBMS blend. That'd be cool.
The danger is thinking that OLAP (HDBMS) is the
total answer. It is almost impossible to avoid
duplication in a hierarchical database. For
transaction processing, I bet that a relational
database will still be the best solution.
