Got one more question today. I am loading data from a file. Data will be inserted or updated in the DB according to whether or not it exists from before.
Keeping track of which objects that comes from the DB (and needs an update()), and which have been new'ed (and needs an Insert) seems like a thing that iBatis users must be doing all the time. Can anyone recommend a pattern for doing this? I can keep of three ways of doing this, with increasing levels of abstractness, but don't know which one to choose. Links or keywords to let me dig up more details on the web also greatly appreciated :) -- Per Magne Bjornerud
