Data analyzing method, apparatus and a method for supporting data analysis

摘要

A data analyzing method, apparatus, and a method for supporting data analysis includes creating or storing a semantic entity repository, wherein the semantic entity repository includes a structured entity set of entities and properties thereof, reference ranges describing the possible values of the properties, and the mappings between the entities and properties and a data structure of a data warehouse. When aggregating data, the entities, properties, and/or property values to be analyzed are selected from the semantic entity repository, and how to calculate at least one measure is defined. The data corresponding to the selected entities, properties, and property values are loaded from the data warehouse according to the mappings, and the at least one measure as defined is calculated.

1. A data analyzing method, comprising the steps of:
creating a semantic entity repository comprising (a) a structured entity set of entities and properties thereof; (b) reference ranges describing possible values of said properties; and (c) a plurality of mappings between said entities, said properties, and a data structure of a data warehouse; selecting, from said semantic entity repository, entities, properties and/or property values to be analyzed; defining how to calculate at least one measure; loading, from said data warehouse, a plurality of data corresponding to the selected entities, properties, and property values according to said mappings; calculating at least one of the defined measures; and marking a time-dependent property and defining mappings to the data warehouse for tracking the variation of the property, wherein said step of defining comprises incorporating an adjusting item related to said variation into the calculation of a measure related to said time-dependent property.
