Fine grain security for analytical datasets

摘要

The technology disclosed relates to assigning field level security to fields extracted from primary sources on a batch basis and compiled into analytical, read-only databases, for ultra-fast, ad-hoc data exploration and faceted navigation on integrated, heterogeneous data sets. The method includes assigning field level security to the extracted fields by combining user selectable inheritance of field level security from source fields that yield the extracted fields, with pinning of inheritance of field level security for the extracted fields to reference fields in the database sources wherein the reference fields are distinct from the extracted fields. The disclosed method also includes receiving additional fields as unsecured data sets, and assigning field level security to the additional fields, received by combining user selectable explicit specification of field level security for the received fields with pinning of inheritance of field level security for the received fields to reference fields in the database sources.
