Can anyone just explain this example in a bit more clear way
To find the name Gallileo in this b-Tree phone book, we:
- Read page 1. This tells us that page 6 starts with Fermat and that page 7 starts with Hawking.
- Read page 6. This tells us that page 350 starts with Fyshe and that page 351 starts with Garibaldi.
- Read page 350, which is a leaf block; we find Gallileo's address and phone number.
