| 20090037462 | SINGLE-OPERATION ON-LINE SCHEMA EVOLUTION - A method for modifying an original data object in a database using a single command is disclosed. The single command is first validated. Once the command has been validated a ghost data object is created using the new definition. The ghost data object is populated with data from the original object. The transaction log records from the original data object are applied to the ghost data object. The original data object is then locked for exclusive access. The final transaction log records from the original data object are applied to the ghost data object. In the final step the database switches to the new data object. Dependent objects are automatically transformed as part of the same operation. | 02-05-2009 |
| 20100114817 | REPLICATION OF OPERATIONS ON OBJECTS DISTRIBUTED IN A STORAGE SYSTEM - One embodiment is a method that reads audit from an audit trail of a source database distributed across multiple storage systems with independent audit trails and then replicates the audit trail to a target database distributed across multiple storage systems with independent audit trails without manual coordination by a database administrator. | 05-06-2010 |
| 20110055158 | DISTRIBUTED DATA ANALYSIS - Distributed data analysis systems and methods are provided. A data broker distributes received data to consumers, such as information and repository consumers, which can be subscribed to the data. A subsystem with a processor for data processing can provide data to the data broker. A first information consumer may include a receiving module for receiving the data from the data broker, an analysis module for analyzing the received data to obtain a result, and a publication module for sending the result to the data broker when a second information consumer is subscribed to the result. | 03-03-2011 |
| 20110093511 | SYSTEM AND METHOD FOR AGGREGATING DATA - There is provided a computer-implemented method of aggregating data. An exemplary method comprises receiving an aggregation scheme and generating numerous first aggregations by aggregating data at a first level of granularity. The data may be associated with a time and stored in a first table. Further, generating the numerous first aggregations may be based on the time and the aggregation scheme. The exemplary method further comprises generating a second aggregation by aggregating the first aggregations at a second level of granularity based on the aggregation scheme. The second level of granularity may comprise the first level of granularity. | 04-21-2011 |
| 20110099160 | SYSTEM AND METHOD FOR EXECUTING QUERIES - There is provided a computer-implemented method of executing a query plan against a database. An exemplary method comprises accessing a first subset of rows of a database table using a direct access method. The query plan may comprise the direct access method. The exemplary method also comprises determining a processing cost of accessing the first subset of rows. The exemplary method further comprises modifying the direct access method in response to determining that the processing cost exceeds a specified threshold. Additionally, the exemplary method comprises accessing a second subset of rows of the database table using the modified direct access method. | 04-28-2011 |

| 20080319668 | Identifying vegetation attributes from LiDAR data - Aspects of the present invention are directed at using LiDAR data to identify attributes of vegetation. In this regard, a method is provided that identifies the location of individual items of vegetation from raw LiDAR data. In one embodiment, the method includes selecting a coordinate position represented in the LiDAR data that generated a return signal. Then, a determination is made regarding whether the selected coordinate position is inside a geographic area allocated to a previously identified item of vegetation. If the selected coordinate position is not within a geographic area allocated to a previously identified item of vegetation, the method determines that the selected coordinate position is associated with a new item of vegetation. In this instance, a digital representation of the new item of vegetation is generated. | 12-25-2008 |
| 20080319673 | Identifying vegetation attributes from LiDAR data - Aspects of the present invention are directed at using LiDAR data to identify attributes of vegetation. In this regard, a method is provided that allocates points to individual items of vegetation from raw LiDAR data. In one embodiment, the method includes selecting a coordinate position represented in the LiDAR data that generated a return signal. Then, a determination is made regarding whether the selected coordinate position is inside a geographic area allocated to a previously identified item of vegetation. If the selected coordinate position is not within a geographic area allocated to a previously identified item of vegetation, the method determines that the selected coordinate position is associated with a new item of vegetation. In this instance, a digital representation of the new item of vegetation is generated. | 12-25-2008 |
