Abstract
A method, apparatus, system, and computer program code for policy-based enforcement in a data virtualization system is provided. Responsive to receiving a query, a computer identifies a virtual object among a set of connected objects that is represented by a set of data assets and their hierarchical relationships. The virtual object corresponds to a subset of the data assets. The computer identifies a subset of objects according to a cumulative transitive closure of the virtual object over the set of connected objects. The computer identifies a set of policies for the subset of objects. For each object in the subset of objects, the computer determines an intermediate decision according to set of policies, whereby a set of intermediate decisions is formed. The computer deterministically reconciles the set of intermediate decisions to generate a resolved decision. The computer provides access to the queried virtual objects based on the resolved decision.
