	abstract = {Though there is much work on how inconsistency indatabases should be managed, there is good reason to believe
that end users will want to bring their domain expertise and
needs to bear in how to deal with inconsistencies. In this
paper, we propose the concept of inconsistency management
policies (IMPs). We show that IMPs are rich enough to spec-
ify many types of inconsistency management methods pro-
posed previously, but provide end users with tools that allow
them to use the policies that they want. Our policies are also
capable of allowing inconsistency to persist in the database or
of eliminating more than a minimal subset of tuples involved
in the inconsistency. We present a formal axiomatic definition
of IMPs and present appropriate complexity results, together
with results linking different IMPs together. We extend the
relational algebra (RA) to incorporate IMPs and present the-
oretical results showing how IMPs and classical RA operators
interact.
