... method createNode. In all other methods it refers to the nodes of the tree using the BTPosition class (i.e., a
widening cast). This layer of abstraction makes it easier to change the specific implementation of a node down the
road – it would only require a change to the one method createNode.

B-tree
In computer science, a B-tree is a tree data structure that keeps data sorted and allows searches, sequential access, insertions, and deletions in logarithmic time. The B-tree is a generalization of a binary search tree in that a node can have more than two children (Comer 1979, p. 123). Unlike self-balancing binary search trees, the B-tree is optimized for systems that read and write large blocks of data. B-trees are a good example of a data structure for external memory. It is commonly used in databases and filesystems.
