instance (chase c i) : s

Repairs a database that may not conform to a set of constraints. It can also be used for data integration in the traditional, relational, regular logic / ED style. If the chase succeeds, the result instance will satisfy the constraints. The options will be used for the construction of the intermediate instances during the chase process.
