The user first enters the DOMAINS area and collects the bag which represents the four domains used in the database. In the SELECT area he has to use as SELECT statement to answer a question that allows him to move on to the JOIN area. Here he looks at how to join the two relations, etc. In the final area he encounters the concept of referential integrity and its connection with domains.

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
