Large Database Strategies

[mudwump]

Like so many on this forum, I have tried so many different PIMs. I really like the structure, capacity and power of Ultra Recall, but I do have a concern for the long term. It is not a limitation of UR, but more of my own limitation. I would like to hear how the various users are planning for the long term with thousands, tens of thousands of pieces of information. How many levels of parent-children? How many items under a single branch before it should be broken down? How to keep the interface uncluttered as much as possible? There are many, many more question than this of course. I am looking for practical strategies.
