A unique identifier of an expression which refers to a cell of a data sheet is stored in a repository. In an application comprising an operation based on evaluating the expression, the expression is indicated by the unique identifier. In response to detecting a write directed to the cell, a modified version of contents of the cell is stored without re-evaluating the expression. The expression is re-evaluated in response to determining that the operation of the application is to be implemented.

Expressions management service for data sheet-based applications

At a data management service, a child template associated with a parent group of one or more cells of a first data sheet is stored. In response to detecting that a parent cell has been added to the parent group, a particular child data sheet is instantiated automatically in accordance with the template. In response to a change to a value in a first cell of the child data sheet, a corresponding value of a cell of the first data sheet is modified.

Network-accessible data management service with web-of-sheets data model

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.

Dynamically materialized views for sheets based data

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.

Dynamically updated data sheets using row links

Representations of a set of cards are displayed via an application authoring interface. A given card represents one or more screen layouts of an application, and contents of a particular card are based on contents of a data sheet materialized in accordance with a data model which enables automatic instantiation of child data sheets associated with a parent cell within a parent data sheet. In response to detecting an edit operation directed at a particular card, an updated representation of the particular card is displayed at the first application authoring interface, and a screen layout corresponding to the updated representation is rendered at a particular mobile computing device.

Application authoring using web-of-sheets data model

At a data management service, an index structure corresponding to a data sheet is stored. The data sheet comprises a grid of cells. An entry of the index structure comprises a reference to content of a cell of the data sheet. In response to a grid structure change of the data sheet, the index entry is automatically updated such that the same content remains referenced from the index entry as before. A result of a computation of an application is obtained using an identifier of the index entry to obtain content from the data sheet. The result is provided to a destination.

Index sheets for robust spreadsheet-based applications

A system and method for analyzing and reporting data from multiple sources is provided. The system is a foundation for an analytical platform that covers not only traditional relational data, but also a new generation of extensible data formats designed for the web, such as those based on XML (FIXML, FpML, ebXML, XBRL, ACORD, etc.), as well as HTML, E-mail, Excel, PDF, and others. In a preferred embodiment, the eXtensible on-line analytical processing (XOLAP), is a scalable client/server platform that allows the multi-dimensional analysis of modern data types, as well as traditional relational data, by bringing them all into an internal common XML-based model, without the time and expense of creating a data warehouse.
