Purpose

ENtree was designed to keep track of the family tree structures that result from the fraternity/sorority tradition of big brothers and big sisters.

This site represents members of the Epsilon Nu chapter of the Kappa Kappa Psi National Honorary Band Service Fraternity, and the Delta Delta chapter of the Tau Beta Sigma National Honorary Band Service Sorority.

Version History

Version 3.0 (current)

Released April 25, 2007. This version was a complete redesign of the underlying database structure. It uses a PostgreSQL database rather than MySQL, because of PostgreSQL's higher compliance with SQL standards. The tree is now stored in a Modified Pre-Order Tree Traversal method, producing much more efficient queries. Where version 2.0 would make one query per person listed in a tree, version 3.0 makes one query per tree. For large trees, this can mean a loading time on the order of hundreds of times faster.

Version 2.0

Released August 2nd, 2004. This version ran from a MySQL database and worked much faster than its predecessor. The tree entries were stored in an adjacency list method. Although using a database, the efficiency of loading one person's family tree was poor.

Version 1.0

Released in January of 2004, this was a complete working version of ENtree. Many major problems had been fixed, especially concerning the look and style.

Version 0.1

This was a testing version of the program released in June of 2003. There weren't many features, it was slow, and the interface was very klunky.
