Selection of certain views of a multidimensional database to materialize may be accomplished using an efficient and effective solution. A set of all potential views may be stored in a structure. A path in the structure may then be traversed in an indicated direction through the structure, the path including two or more potential views and beginning at an indicated view. Then two or more immaterialized views in the path may be compared to each other to determine which immaterialized view is the o...

A method for displaying multidimensional data on a screen of a display device, includes assigning a first dimension element, having been selected by a user from among the multidimensional data, to an axis; giving weights to a plurality of member regions using a function of number of data belonging to respective members of the first dimension element; defining the weighted member regions as a plurality of regions on the axis, which are partitioned for the respective members of the first dimension...

An apparatus for processing image data 603, 604 is provided, which comprises processing means 201, 202, memory means 205, 206, 207, display means 104 and manually operable input means 102, 103, 105, 106, wherein said memory means stores said image data and instructions 602, said image data and said instructions configure said processing means to perform the steps of outputting said image data to said display means as a hierarchical structure 603 of image data processing nodes 303, 401 to 413 hav...

This disclosure describes techniques of validating data that a user enters into an enterprise system for storage within a multidimensional data cube. The data cube includes one or more data hyperplanes associated with members of a dimension having cells that contain data. In addition, the data cube includes a validation rule hyperplane of the dimension. Cells in the validation rule hyperplane contain data that indicate whether data in corresponding cells of the data hyperplanes comply with a val...

A technique to implement an integrated multidimensional sorter is to store data such that it may be retrieved in a sorted fashion. Entries are stored into a memory according to time stamp value, and the time stamp value is divided into multiple portions. The memory is organized as a pointer memory. An integrated multidimensional sorter may be implemented using integrated circuit technology using one or more integrated circuits. These integrated circuits may be used in management of network traff...

The cost of running a query (having a query range) on a multidimensional database may be estimated using a process factors criteria beyond merely the number of affected records. First, a materialized view of the database may be represented as a container of tuples, sorted by key. Then keys may be stepped through, each key representing a mapping of a combination of tuples from the container. At each step, the process may request the next smallest key in the query range greater than or equal to th...

A multi-dimensional database query to be sent to a data source may be split into multiple smaller queries by a mid-tier solution and sent individually to the data source(s) for calculation and retrieval of data. This may be accomplished by creating row and column tree structures representing title and header rows and header columns in the query grid. The operation to be performed by the query may then be performed on these tree structures. The grid may then be split based on the resulting tree s...

Sampling may be supported in a multidimensional database by integrating it into metadata and/or data navigation requests. Additionally, biasing may be introduced to allow a user to focus results.

A method of distributing research data from a common database to a user of the common database is provided. Data concerning research results and data upon which the research results are based are stored in a local database and are linked to each other. Data concerning research results and data upon which the research results are based are selectively extracted from the local database to the common database. Research data are then selected by a user of the common database from the extracted data ...

A multidimensional beamforming device that performs consecutive one-dimensional operations. For example, beamsteering for a two-dimensional array can be include a projection of a beam onto each of the respective axes of the array. In such a device, a first beamforming processing element is used to form multiple beams for each array output along a given row. In a preferred embodiment, sequential output vectors from the first processing element are then applied to a transposing or corner turning m...
