Embodiments of the present invention provide systems and methods for visualizing and querying data. Data subsets within an original table are examined. Values within the data subsets are extracted. Based on the extracted values, a new table is generated. The data contents of the original table differ from the data contents of the new table. Thus, the resulting visualization of the original table differs from the resulting visualization of the new table.

Querying and projecting values within sets in a table dataset

In one example, a method comprises receiving, with a data access service, an input query from an enterprise software application, wherein the data access service is positioned between the enterprise software application and a multidimensional data source; parsing the input query into a parse tree; generating an abstract syntax tree based on the parse tree, the abstract syntax tree comprising input query elements and multidimensional expression query elements based on the input query; performing an evaluation of metadata comprised in the multidimensional expression query elements of the abstract syntax tree; restructuring the abstract syntax tree based on the evaluation of the metadata; executing a query based on the restructured abstract syntax tree on the multidimensional data source; and retrieving a query result set from the multidimensional data source comprising results that are responsive to the query based on the restructured abstract syntax tree.
