Using a Trie would make a lot of sense here.
Say what you desire to store are phone numbers, at the leaf nodes we could save the name of the contact.
This would enable us with a quick search (number based) , add or delete/edit operation in optimized space.

I am guessing further applying some compression algorithm over the Trie could further optimize the space usage.
Please correct me if I'm wrong.
