  • Patent number: 9576024
    Abstract: An improved system and method for query processing in a distributed column chunk data store is provided. A distributed column chunk data store may be provided by multiple storage servers operably coupled to a network. A storage server provided may include a database engine for partitioning a data table into the column chunks for distributing across multiple storage servers, a storage shared memory for storing the column chunks during processing of semantic operations performed on the column chunks, and a storage services manager for striping column chunks of a partitioned data table across multiple storage servers. Query processing may be performed by storage servers or query processing servers operably coupled by a network to storage servers in the column chunk data store. To do so, a hierarchy of servers may be dynamically determined to process execution steps of a query transformed for distributed processing.

  • Patent number: 8112458
    Abstract: A facility for defining a distinguished segment of individuals within a population of individuals is described. The facility displays a prompt for user input specifying a natural-language characterization of a segment membership criterion for identifying individuals who are members of the distinguished segment. The facility then receives, in response to the displayed prompt, user input specifying a natural-language characterization of a segment membership criterion for identifying individuals who are members of the distinguished segment.

  • Patent number: 7464122
    Abstract: A method, system and computer-readable medium for analyzing interaction or usage data, such as for customers, is described. The interaction or usage data may be stored in log files and supplemented with data from other sources. Various data parsing information may be defined and used as part of the analysis, such as by using customer-specific information to identify various occurrences of interest. For example, when analyzing a customer's web site interaction data, the parser component can use data defining customer-specific types of web site events of interest. Such high-level types of occurrences can be specified in a variety of ways, such as by using a combination of a logical web site, one or more URIs corresponding to web pages, and/or one or more query strings. The data parsing information may also specify a mapping of actual web sites to one or more logical sites.

A storage server provided may include a database engine for partitioning a data table into the column chunks for distributing across multiple storage servers, a storage shared memory for storing the column chunks during processing of semantic operations performed on the column chunks, and a storage services manager for striping column chunks of a partitioned data table across multiple storage servers. Any data table may be flexibly partitioned into column chunks using one or more columns with various partitioning methods. Update data may then be incrementally imported as separate column chunks that may later be merged with the column chunks of the partitioned data table.
