    摘要: Systems, clients, servers, methods, and computer-readable media of varying scope are described in which, two extensions for a multidimensional database query language extensions, AddCalculatedMembers and StripCalculatedMembers, allow an OLAP client to easily control the integration of calculated members into the results of OLAP database queries. The OLAP client need not be aware of the details of which calculated members are defined within the multidimensional database and need not explicitly request the inclusion or removal of each calculate member from the output data set of the query.

    摘要: A method for providing workload information in a structured workload information data structure format that is organized according to a workload schema to be conducive to a given end usage of the information. The structured workload information can be made accessible using standard database analytical server applications to facilitate ad-hoc querying of the structured workload information to summarize and analyze the database workload or to facilitate exchange of workload information. A structured workload information (SWI) is constructed according to a SWI schema to facilitate a desired end usage of the workload information. The query information is extracted from the workload and stored in a structured workload information (SWI) data structure according to the schema based on the desired end usage of the information such as ad hoc querying or information exchange. The query information may be stored in a relational database having query information organized as a central fact table and a collection of hierarchical dimension tables or as an OLAP cube featuring hierarchical dimensions that arrange the query information in dimensions having objects ordered as a function of granularity or the information may be stored according to an XML schema wherein units of query information are separated by XML tags that identify a type of workload information.

    摘要: A system for editing the dimension structure associated with a data cube is revealed. The editing may be used to enforce given criteria on the cube. This includes modifying the cube in order to satisfy regulations requiring researchers to protect information about individuals, such as medical, genealogy and genetics records. The inference control methods disclosed therefore enable safe aggregated datasets to be released to researchers. When combined with information theoretic methods, the invention method of editing the dimension structures may be used to express clearly and discover correlations that exist in the dataset. This mining of the data and editing of the dimension structure allows the user of a simple multidimensional cube viewer to visually verify the patterns discovered.

    摘要: Techniques are provided which address the problems associated with the conventional approaches for storing multidimensional data in a relational database system. According to technique, the many foreign key values of each row in the fact table are mapped to and replaced by a nullreplacementnull value. A mapping function is provided that derives a replacement value from any given combination of foreign key values, and an inverse mapping function is provided to reproduce the combination of foreign key values given the replacement value. A mapping function is selected such that the foreign key value combinations of multidimensional values that are conceptually related to each other map to values that are close to each other. The rows in the fact table are then stored within the fact table in the sorted order, thus causing values that are conceptually related to each other to be stored physically near each other within the fact table. Various techniques are provided for generating the replacement value from the foreign key values by subdividing the multidimensional cube that contains all of the multidimensional values into smaller sub-cubes that are referred to as tiles. Variations on the tiling mechanism are provided. According to one approach, the cube is sub-divided into tiles based on the members of a particular level of a hierarchical dimension. According to another tiling approach, the tiles themselves may be subdivided into smaller tiles to create a hierarchy of tiles.

    摘要: There is provided a method for providing a function for use in detecting a presence of an exception in multidimensional data. The method comprises the steps of (a) partitioning the multidimensional data into at least a first region and a second region; (b) assigning a first region-specific function to the first region and a second region-specific function to the second region; and (c) determining a combined function from the first region-specific function and the second region-specific function. The combined function is used to calculate an expected value of the multidimensional data for distinguishing the presence of an exception.

    摘要: A method for processing requests includes receiving, from a requestor, a first read request to read a portion of a seismic cube. The first read request includes a virtual location of the portion. The method further includes querying a seismic cube index to obtain a mapping parameter and a storage location of a section including the portion of the seismic cube. The mapping parameter maps virtual locations in the seismic cube with data locations in the section. The section is identified using the virtual location of the portion. The method further includes calculating, on a computer processor and using the mapping parameter, a data location in the section corresponding to the virtual location of the portion, and transmitting a second read request to the storage location of the section. The second read request includes the data location. The requestor receives the portion from the storage location.

    摘要: Systems and computer program products that identify data that is related to and associated with data that has been selected from a multidimensional database. The overwhelming amount of data in a multidimensional database that may be viewed by a user, such as a data analyst, is reduced to the selected and associated data by use of index data and related index data, according to the present invention. The views of selected data and related data may be highlighted and formatted for presentation to the user. Further, irrelevant data is filtered out and not presented to the user. Existing systems have not been able to efficiently and adequately identify data that is related to and associated with selected data in a multidimensional database.
