Yes this is a particular problem and will no doubt be the sticking point to any conversation here. The most fundamental lesson of modern database theory has been the realization that pointers aren't necessary to achieve anything where data manipulation is concerned.
Its also a particularly difficult change in perspective if one is using OO methodology, with its network approach, day in day out. One should not underestimate the wrench that this shift in mindsets requires (and that presupposes a willingness to make the attempt in the first place).
Nonetheless, a question that I would like to ask is whether OO requires pointers - are they inseparably ingrained in to the whole methodology or could some hypothetical programming approach still be considered OO even if it did away with OIDs?
