Anomaly detection in data perspectives
First Claim
1. A system that facilitates data perspective analysis, comprising:
- a component that receives at least one data perspective; and
an anomaly detection component that automatically analyzes the data perspective to detect at least one data anomaly via a curve fitting process applied to continuous and/or discrete data from a data tube;
the data tube comprising a data slice that includes at least one data cell of the data perspective in which only one data dimension varies.

Abstract
The present invention leverages curve fitting data techniques to provide automatic detection of data anomalies in a “data tube” from a data perspective, allowing, for example, detection of data anomalies such as on-screen, drill down, and drill across data anomalies in, for example, pivot tables and/or OLAP cubes. It determines if data substantially deviates from a predicted value established by a curve fitting process such as, for example, a piece-wise linear function applied to the data tube. A threshold value can also be employed by the present invention to facilitate in determining a degree of deviation necessary before a data value is considered anomalous. The threshold value can be supplied dynamically and/or statically by a system and/or a user via a user interface. Additionally, the present invention provides an indication to a user of the type and location of a detected anomaly from a top level data perspective.
