Flexible data schema in a database?
I figured I pose this to the list and see if any one can build a
better mousetrap.
The problem:
1. Store hierarchical data in a database, but without knowing the
hierarchy beforehand.
2. Allow the user to define there own hierarchy, and allow the system
to support multiple hierarchies.
Call it a cataloging system, we have an object and we want to add data
about that object to the system.
