  • Query management system and engine allowing for efficient query execution on raw details
    Patent number: 9298754
    Abstract: A database system maintains a feature set of a modern database system while operating directly on raw data files. Systems may use an adaptive indexing mechanism that maintains positional information to provide efficient access to raw data files, a flexible caching structure, and techniques for selective parsing and selective tokenizing. In doing so, possible performance bottlenecks associated with repeated parsing, tokenizing, and expensive data type conversion costs can be overcome.
    Type: Grant

    Date of Patent: March 29, 2016
    Assignee: Ecole Polytechnique Federale de Lausanne (EPFL) (027559)
