BTREE: A FORTRAN Code for B+ Tree

摘要

This report contains documentation for a FORTRAN implementation of a B+ tree, a data structure which is often used as the foundation of a database manager. Because the code is written in a high-level language, it is basically transportable to any computer with FORTRAN capability (minor modification may be required for compatability with a host computer's operating system and compiler). The work was done as a first step towards developing user-friendly, interactive database manager needed by U31 to support studies requiring the extensive use of minefield planning codes.
