Abstract: In response to a determination that a first logical table is to be created in a data sheet, a respective row identifier is generated and stored for individual rows of the first logical table. To indicate a relationship between a particular cell of another logical table and a particular row of the first logical table, the row identifier of the particular row is stored. After a modification of a value stored in the particular row, the row identifier is used to determine an updated value to be displayed in the particular cell of the other logical table.

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.
