Allan, Please can you explain to your audience how long have you been around and how long have you been workling with Adabas, IMS and DB2 ?
Please define also what type of work have you been doing with all these Database software packages, if you can still remember.. Why ? In the USA there is lots of people that claim that they are "experts".. specially if they work in a cage for a big company.
