12.6. B-Trees — CS3 Data Structures & Algorithms12.6.1. B-Trees¶ This module presents the B-tree. B-trees are usually attributed to R. Bayer and E. McCreight who described the B-tree in a 1972 paper. By 1979, B-trees had replaced virtually all large-file access methods other than hashing. B-trees, or some variant of B-trees, are the standard file organization for applications requiring insertion, deletion, and key range searches. They are used
