Abstract: Systems and methods disclosed herein are used to store and interact with data from heterogeneous data sources. In some embodiments, a method of improved querying of data includes: identifying a data value in a first data source of a plurality of heterogeneous data sources. The method further includes: (i) extracting, from the first data source, one or more characteristics associated with the data value, (ii) creating a cell that includes the data value and the extracted one or more characteristics, and (iii) storing, in an unordered collection of cells, the created cell. The method also includes: receiving a query that specifies a set of one or more required characteristics. In accordance with a determination that the created cell includes each required characteristic in the set, the method includes locating the created cell and presenting, on an electronic device's display, a tabular representation that at least includes the data value.
