Patent Number Title Of Patent Date Issued
8126926 Data visualization with summary graphs February 28, 2012
Systems, methods, and other embodiments associated with visualizing data using summary graphs are described. One example method includes constructing a summary graph for display. The summary graph represents the data as a summary node having a plurality of property edges connected to
8015180 Queries with hard time constraints September 6, 2011
Systems, methodologies, media, and other embodiments associated with supporting queries with hard time constraints are described. One exemplary system embodiment includes logic for accepting a query having a hard time constraint. The example system may also include logic for selectiv
7996387 Techniques for extending user-defined indexes with auxiliary properties August 9, 2011
In one embodiment, a database server registers one or more functions included in a user-defined index that includes one or more auxiliary properties. The one or more functions are operable to generate index entries of the user-defined index for the one or more auxiliary properties. T
7987164 Method and system for speeding up rebuild of user-defined indexes during partition maintenance o July 26, 2011
A method, system, and computer program product provides improved performance for rebuild of user-defined indexes during partition maintenance operations (partition split, merge, and move). A method of maintaining a index of a partitioned database table comprises performing a partitio
7953728 Queries with soft time constraints May 31, 2011
Systems, methodologies, media, and other embodiments associated with supporting queries with soft time constraints are described. One exemplary system embodiment includes logic for accepting a query having a soft time constraint. The example system may also include logic for rewritin
7925647 Techniques for optimizing SQL statements using user-defined indexes with auxiliary properties April 12, 2011
In one embodiment, a database server registers one or more functions included in a user-defined index that includes one or more auxiliary properties. The database server receives a query that specifies one or more parameters. A query optimizer generates a plurality of execution plans
7844600 Materialized views with user-defined aggregates November 30, 2010
Systems, methodologies, media, and other embodiments associated with supporting materialized views with user-defined aggregates are described. One example system includes logic for exposing a set of interface actions to support a user-defined aggregate in a materialized view associated
7774346 Indexes that are based on bitmap values and that use summary bitmap values August 10, 2010
A database management system that has bitmap values in which set bits in a representation of a bitstring specify a set of objects whose definitions are built into the database management system. The database management system further includes user-accessible operations on the bitmap valu
7617235 Method and system for creating a domain index November 10, 2009
A domain index for a partitioned database can be created using a user-defined indexing scheme. Partition maintenance operations performed on the partitioned database objects cause corresponding partition maintenance operations to be performed on the domain indexes. The user-supplied
6920460 Systems and methods for managing partitioned indexes that are created and maintained by user-def July 19, 2005
Domain indexes (indexes created and maintained by user-defined indexing schemes) are managed on partitioned database objects that store data using a system-managed approach. Partition maintenance operations performed on the partitioned database objects cause corresponding partition maint
6360228 Transactional framework for executing statements involving non-native code March 19, 2002
Described herein is a framework for providing statement atomicity for DDL statements. The framework allows the ability to perform, as multiple transactions, the DDL operations specified by a DDL statement. To begin execution of a DDL statement, a DBMS, for example, updates a flag to
