If you have such kind of structure ensures that once a query is raised, traversal is quite faster and you get quick results. Later on, indexes and tables manage data with the use of separate B-tree structure which is known as B+ tree.

The header occupies the first two pages of Exchange database EDB file. It means that the first logical page of the database is indeed its third physical page.
