  • Range predicate canonization for translating a query
    Patent number: 8799271
    Abstract: A system and methods for implementing a materialized view for a query are provided. The query system includes a database that includes a base table. The base table can include a set of data. The query system also includes a materialized view associated with a portion of the set of data, and a MVQR component to translate each of a range predicate of the materialized view and a range predicate of a query into a canonical range representation (CRR) format in materialized view metadata and query metadata, respectively, to enable the query to search the materialized view.

  • Method for execution of query to search strings of characters that match pattern with a target string utilizing bit vector
    Patent number: 6785677
    Abstract: The method of the present invention is useful in a computer system including at least one client. The program executes a method for matching a pattern string with a target string, where either string can contain single or multi-character wild cards. The method includes the steps of preprocessing the pattern string into a prefix segment, a suffix segment, and zero or more interior segments. Next, matching the prefix segment, the suffix segment, and the interior segment(s) with the target string.
