Abstract
Enforcement of policies for tabular data access as a collection of columns over a plurality of different information assets is provided. In an enforcement knowledge graph, information asset-assigned terms are found that correspond to information assets in a virtual information asset that references a set of tabular data. Transitive closures of the information asset-assigned terms are found in a business glossary to form a table of business glossary terms. Term intersection is determined between a hash table of any column-assigned terms and the table of business glossary terms. The information assets are assigned to the virtual information asset when the term intersection is not empty. A set of policy rules associated with the set of tabular data and a context of a user making a data access request to the set of tabular data is applied to the virtual information asset to determine an access enforcement decision.
