  • Virtualizing objects within queries
    Patent number: 7917547
    Abstract: The present invention extends to methods, systems, and computer program products for virtualizing objects within queries. Embodiments of the invention virtualize data access for use with queries. Virtualization can be implemented within any portion of a syntax tree. For example, data can be virtualized for a property of an object that is itself another object. Data virtualization facilitates lazy evaluation of query expressions. That is, actual property values for properties within a data construction statement are virtualized until a query specifically requests the actual property values. Further, data virtualization also conserves resources and results in more efficient query evaluations.
