I need to present a 90 minute lecture on databases, what they are and how work in a not very technical way to my CEO who wants to know more and to understand them. I'll need to start from the very basics such as what is table etc. Has anyone in the list given such a presentation. If so can you share you experience and some pointers. Also if you know of a PowerPoint (or similar) that would be helpful, could you point me to it. Thanks, Ken -- //www.freelists.org/webpage/oracle-l
