Latest Patents
One of his latest patents is titled "Persisted data views supporting access control." This invention enforces user access rights to a data view by initially generating a replication table of the view. The replication table includes all view data to which any user is entitled. This table is generated during a first database session with a specific value for a session variable. A data access control structure is then applied to the replication table to produce output comprising a subset of the view data for a specific user during a second database session. This method conserves processing resources in later stages when access control structures are applied to grant view access rights to particular users.
Another significant patent is "Using workload data to train error classification model." This invention involves acquiring a database system workload comprising multiple database queries and replaying this workload on various database systems to generate failed events. Each failed event is associated with multiple attributes, and a root cause is assigned to each event. The classification model is then trained based on these failed events and their assigned root causes to infer an output root cause based on input attributes.
