There are many data management problems for which nobody has ever proposed any sort of solution. For some problems, no solution may exist.

Even if one overcomes the incompetence and carelessness, one is still faced with malice. Network model databases use some form of logical or physical pointer (OID) for identity. Relational model databases use candidate keys for identity. Neither provide protection against the growing problem of identity theft.

The proposed solutions to many other data management problems are, at best, poor compromises. Missing information springs to mind. Received on Wed Jun 06 2001 - 03:38:52 CEST
