Abstract
Embodiments of the present invention provide a system and method for summarizing and reporting the impact of database statements at a database appliance. The database appliance, according to one embodiment, can receive a database request and determine a set of information related to the request. Embodiments disclosed herein take in as input the database statement text and output multiple impact vectors, each containing both the name of an affected entity and a 32-bit “impact bitmap” for that entity. This concise and unambiguous output format can be computed using fast AND, OR, XOR, and NOT operations, allowing for highly efficient evaluation of database statements against user defined policies and finer policy granularity.
