File Hierarchies and Reorganisation

Synopsis

Looks at the way in which British Airways use computers for seat reservations. Animations show how files are structured with a hierarchy of indexes to allow fast access to static information about flights. First an airline index is searched sequentially, and then a binary search is used on a flight number index to find detailed information about the flight.

Notes

NB. As of May 2016 Open University Worldwide are no longer distributing DVDs. They have posted this message on their website: ‘Unfortunately Open University Worldwide Limited has decided that product sales are no longer viable given the reduced funding to Higher Education institutions and diminishing demand for the products we have traditionally stocked. At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
