Embodiment Construction

[0015] The above, together with other features, will become apparent with reference to the accompanying specification, claims and drawings. Specific details are set forth in order to provide an understanding of various embodiments. It will be apparent, however, that various embodiments may be practiced without these specific details. The accompanying description and drawings are not limiting.

[0016] Multidimensional database environments, examples of which include Oracle Essbase, can be used to integrate large amounts of data (in some cases from multiple data sources) in a manner that addresses the specific requirements of end users, and distribute filtered information to these users.

[0017] figure 1 An example of a multidimensional database environment 100 is illustrated in accordance with an embodiment.

[0018] like figure 1 As shown, according to an embodiment, a multidimensional database environment operating as a database tier may include one or more multidimensi...

Abstract

In accordance with an embodiment, described herein is a system and method for automatic inference of a cube schema from a tabular data for use in a multidimensional database environment. A cube schemainference component can successively perform column-wise splits to calculate information gain ratios between each pair of a plurality of columns in the tabular data. A cross correlation matrix can beconstructed from the information gain ratios between each pair of columns. The system can determine relationships among the plurality of columns based on the cross correlation matrix; create a hierarchy directed graph to represent the relationships; and further transform the hierarchy directed graph into a cube schema that can be used to create a cube for loading the tabular data, or to map the tabular data into an existing cube in the multidimensional database environment.
