Thank you for the responses, but I was thinking more along the lines of slowly-chaning dimension, rather then audit/logging. In one of the earlier comments Jeff Storm showed a portion of his solution, which is closer to what I am after. I would like for the application to be able to "look" at the same data using different hierarchy structures (Hierarchy A, which existed at time X and Hierarchy B, which existed at time Y) and all of them have to be equally accessible in the same set of tables.Thank you!
The usual solution for that is adding effective dates to the table, and using those in your queries.
That often has a significant impact on performance, and always makes coding a bit more complex, but it does work.
