Abstract
Techniques for determining user authorization to access data in dynamically generated database structures are presented. A method can commence upon receiving database statements from a user that is authorized to access a set of data in a database. A physical plan derived from the received database statements to operate on the database is inspected for references to dynamically generated data structures such as aggregates. A modified physical plan having no aggregates and/or other altered database structures is used to issue low latency database statements to operation on the database for verifying user access authorization to the underlying data. In some cases, the foregoing database statements are based on a virtual multidimensional data model. In other cases, a low latency directive is included in the modified physical plan to facilitate a low latency authorization response.
