Abstract: Join key propagation including receiving a request to generate a referencing worksheet linked from a data source worksheet, wherein the data source worksheet is a presentation of a data set organized in columns from two data source tables joined using a join key, and wherein the referencing worksheet presents at least a subset of the data set presented by the data source worksheet; retrieving data source worksheet metadata and the join key using a reference to the data source worksheet metadata in the request; determining an additional column from the two data source tables to add to the referencing worksheet, wherein the additional column is excluded from the data source worksheet; and creating, using the data source worksheet metadata and the join key, the referencing worksheet presenting the columns from the two data source tables with the additional column.
Abstract: Compiling a database query including receiving, by a query compiler from a client computing system, a state specification of a graphical user interface comprising a worksheet, wherein the worksheet is a presentation of a data set from a data warehouse; converting, by the query compiler, the state specification into a worksheet algebra including determining a first order of operations for elements within the state specification, wherein the worksheet algebra comprises the first order of operations over a nested table; converting, by the query compiler, the worksheet algebra into a database query; and sending the database query to the data warehouse.

Abstract: Maintaining cardinality of rows while joining worksheets from a database including receiving a request to join, to a first worksheet, a second worksheet from the database; for each row in the first worksheet: generating a join row for data from the second worksheet on the database; in response to determining that there is at least one matching row in the second worksheet on the database: compare a maximum value and a minimum value for each column in each row of the at least one matching row; if the maximum value and the minimum value match, store a matching value in a corresponding column of the join row; and if the maximum value and the minimum value do not match, store a multiple value indication in the corresponding column of the join row; and presenting the join row adjacent to a corresponding row in the first worksheet.

Abstract: Enabling editable tables on a cloud-based data warehouse including receiving, by a query manager, a client-provided table; receiving, by the query manager from a query manager client, a request to create a referencing worksheet using, as data sources, the client-provided table and a database table on a cloud-based data warehouse; storing, by the query manager, the client-provided table in the schema storage location on the cloud-based data warehouse, wherein the schema storage location is a storage location on the cloud-based data warehouse to which the query manager has read and write access, and wherein the database table is external to the schema storage location; generating, by the query manager, a database query to create the referencing worksheet, wherein the database query targets the client-provided table in the schema storage location and the database table; and issuing, by the query manager, the database query to the cloud-based data warehouse.
