INHERITED DIMENSIONS

摘要

Techniques are described for inheritance of dimensional attributes in multidimensional datasets. In some embodiments, an inherited dimension comprises one or more base dimension objects and one or more specialized dimension objects that are stored in a non-transitory volatile or non-volatile computer-readable storage. Each base dimension object of the one or more base dimension objects has a first set of dimension attributes that are common across the plurality of multidimensional datasets. The one or more specialized dimension objects include a specialized dimension object that has a second set of dimension attributes for a particular multidimensional dataset from the plurality of multidimensional datasets. In response to receiving a query that references the dimension and targets the particular multidimensional dataset, a base dimension object and the specialized dimension object are accessed to generate a query result.

1. A method comprising:
storing, for a dimension that is associated with a plurality of multidimensional datasets, one or more base dimension objects; wherein a base dimension object of the one or more base dimension objects has a first set of dimension attributes that are common across the plurality of multidimensional datasets; storing, for a particular multidimensional dataset of the plurality of multidimensional datasets, a specialized dimension object that extends the base dimension object of the one or more base dimension objects; wherein the specialized dimension object has a second set of dimension attributes for a particular multidimensional dataset from the plurality of multidimensional datasets; wherein the second set of dimension attributes are not in one or more other multidimensional datasets of the plural of multidimensional datasets; in response to receiving a query that references the dimension and targets the particular multidimensional dataset,
accessing a base dimension object of the one or more base dimension objects and the specialized dimension object; andgenerating a set of one or more results for the query based on the base dimension object and the specialized dimension object.
