Abstract
Methods, systems and articles of manufacture are provided for a query analysis approach used to identify 'nondestructive' and 'destructive' queries. In one aspect, a 'non-destructive' query is one which does not return any additional results relative to results returned by a previously executed query or queries. Conversely, a 'destructive' query is one which does return additional results relative to results returned by a previously executed query. If the query is determined to be destructive, the query is executed against the complete data repository (e.g., database or data warehouse). If the query is nondestructive, the query (or some restructured form thereof) is executed against a data subset of the complete data repository.
