How do you plan to keep your tree represented??
There are quite a few options for this.
Extensive talk has been made in this list.
Also search the archives.
Basically you can follow
- nested trees (pure sql) aproach
- Genealogical tree representation approach
(either using text to represent the path to the parent (pure sql), or
arrays)
- The contrib/tree implementation
