Abstract: A descriptor of a dynamically materialized view is stored. The descriptor includes a query to select a subset of cells from a data sheet, and a result of executing the query. In response to an update directed to the data sheet, the result stored in the descriptor is modified based on re-executing the query, and a notification is transmitted to an execution platform at which an application whose output depends on the dynamically materialized view runs.
