I have been asked to work with the section in Copenhagen receiving the Ukrainian refugees. So many good hands-on people work on it, but we need to build an efficient database associating people with children, parents, metadata to assist in what needs to be done, like placing the families with children close to where schools have capacity and the like.
The Danish social security number is a key to all citizens, but these new arrivals do not have them, so this runs entirely in parallel.
