I haven't viewed the video yet, I will tomorrow at work. From everybody's comments, it sounds very interesting. Regarding your comment on data generators. I can say that I have (in our company product) a very similar data structure as you described above. I have created a "data generator" for our product and it does work with our complex data model. It generates realistic data, not just random text garbage (that is indeed useless - maybe this is what you were referring too). We used the data generator for performance testing. Populating for example our Learner table with 500 000 learners (and there related data - like addresses, subjects, schools etc), and then see where any bottlenecks occur in our UI or SQL. I think tiOPF's demo 21 uses a similar data generator to what I created in our Master Maths product. Our company product just uses a much greater scale of generated data. So bottom line - a realistic data generator can be very useful. -- Regards, - Graeme - _______________________________________________ fpGUI - a cross-platform Free Pascal GUI toolkit http://fpgui.sourceforge.net _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
