Abstract: A computing device displays a data visualization user interface that includes a schema region. Each data field displayed in the schema region is visually associated with a respective data object of a plurality of data objects in an object model. The device receives user input to specify a mathematical expression that includes a first data field from a first object and a second data field from a second object. The first object and the second object are distinct objects in the object model. The device generates a calculated data field based on the mathematical expression. The device assigns the calculated data field as a member of a third object in the object model according to relations in the object model connecting the first object to the second object. The device displays the calculated data field, in the schema region, visually associated with the third object.

Abstract: A method for analyzing data from data sources includes receiving user selection of a data source and displaying an interface that includes a schema region and a plurality of shelf regions. Each data field in the schema region is associated with a respective system-defined object from the data source. In a first display mode, each data field is displayed as associated with a respective system-defined object. In a second display mode, each data field is displayed in a respective user-defined folder. The method also includes displaying a data visualization according to a user placement of first and second data fields into the first and second shelf regions.

Abstract: A method for analyzing data from data sources includes receiving user input to specify a mathematical expression. The mathematical expression includes a first data field from a first object and a second data field from a second object. The first object and the second object are distinct objects of an object model that includes a tree in which each relation between objects represents a respective many-to-one relationship between respective objects. The method further includes generating a calculated data field based on the mathematical expression, and assigning the calculated data field as a member of a third object in the object model according to relations in the tree connecting the first object to the second object.

In a first display mode, each data field is displayed as associated with a respective system-defined object. The method also includes receiving, in the first display mode, user placement of a first data field into a first shelf region. In a second display mode, each data field is displayed in a respective user-defined folder. The user-defined folders are distinct from the system-defined objects. The method also includes generating a data visualization according to the user placement of the first and second data fields into the first and second shelf regions.
