This is Dr. Jochen Eckert of DB Systems, who's going to tell us about train scheduling using Cincom Smalltalk:

The goal of this project: They needed to accurately schedule their trains with correct times, and without conflicting train paths. They have 40,000 trains/day, over 35,000 km of tracks. They needed:

  • a GUI for Visualization and user interaction
  • Detailed calculation of running times. times of usage, conflicts
  • Multi-user access - 7 regional business units, around 50 users per unit.

The client is a VW 7.4.1 "fat client" connected to an Oracle 9 DB and some Smalltalk servers. There's also a lighter weight version for notebooks that uses personal Oracle.
