Business Intelligence Document

摘要

A business intelligence (BI) document preserves references to identities and formats of remote data sources and allows a local computing device to offload analytical operations to remote data sources. The BI document specifies a graph of entities connected by directed edges from the output of one entity to an input of another entity. An entity, for example, can represent without limitation a data structure, an external data source, a control element, an external event source, a visualization, or an update service. The entities of a BI document at a local computing device can reference data at an original data source—rather than extracting data from the original data source to a preferred local datastore. An entity of the BI document can direct a remote data source to execute transformations on the remote data before returning a solution to the local computing device.

主权项

1. A method comprising:
receiving into memory of a local computing system a description of one or more pipeline-connected entities defining an application, wherein the one or more pipeline-connected entities include a first entity including one or more expressions and designating a remote data source for evaluation of the one or more expressions of the first entity by the remote data source, a second entity including one or more expressions and designating data of the local computing device against which the one or more expressions of the second entity are to be locally evaluated, and a visualization entity including one or more expressions defining a user interface; updating the one or more connected entities in memory based on a remotely computed result of the first entity and a locally computed result of the second entity; and presenting at least one of the remotely computed result of the first entity and the locally computed result of the second entity via the user interface defined by the visualization entity.
