8. An apparatus comprising:

one or more processors, and

memory storing processor-executable instructions that, when executed by the one or more processors, cause the apparatus to:

determine, based on the one or more changes, an updated selection state for the handle, wherein the handle indicates, prior to performance of the one or more operations, an initial selection state of the table data via the row and the at least one column for each data table of the plurality of data tables, wherein the initial selection state indicates an association or a lack of an association between the first attribute and the table data stored in the plurality of data tables; and

cause, based on the updated selection state, the handle to be updated by retrieving one or more data values from the table data associated with the one or more changes, wherein the updated handle comprises the updated selection state and indicates, based on the retrieved one or more data values associated with the one or more changes, an association or a lack of an association between the first attribute and the table data.

9. The apparatus of claim 8 , wherein the updated selection state indicates, for each row of each data table of the plurality of data tables, that data stored in the corresponding row is associated or not associated with the first attribute.

10. The apparatus of claim 8 , wherein the updated selection state differs at least partially from the initial selection state based on the one or more changes.

11. The apparatus of claim 8 , wherein the updated selection state comprises an indication of one or more rows of the plurality of data tables that are not indicated by the initial selection state for the first attribute.

12. The apparatus of claim 8 , wherein the processor-executable instructions that cause the apparatus to determine the one or more changes to the table data further cause the apparatus to:

receive an indication of a selection at a user interface of a graphical object associated with the first attribute;

cause, based on the selection at the user interface, the one or more operations to be performed on the table data associated with the first attribute;

modify, based on a result of the one or more operations, the table data; and

determine, based on the modified table data, the one or more changes.

13. The apparatus of claim 8 , wherein the processor-executable instructions that cause the apparatus to determine the one or more changes further cause the apparatus to at least one of:

receive one or more modifications to the table data associated with the first attribute; or

receive new data associated with the first attribute.

14. The apparatus of claim 8 , wherein the first attribute is one of a plurality of attributes, and wherein the processor-executable instructions further cause the apparatus to:

determine, for each attribute of the plurality of attributes, an initial selection state comprising an indication of one or more rows of the plurality of data tables comprising data associated with the corresponding attribute; and

generate, for each attribute of the plurality of attributes, a handle comprising an indication of the initial selection state for the corresponding attribute.

15. A non-transitory computer-readable storage medium comprising processor-executable instructions that, when executed by one or more processors of a computing device, cause the computing device to:

determine, based on one or more operations performed on data associated with a first attribute and a handle for the first attribute, one or more changes to table data associated with the first attribute and stored in a plurality of data tables, wherein the handle comprises a row and at least one column for each data table of the plurality of data tables;

determine, based on the one or more changes, an updated selection state for the handle, wherein the handle indicates, prior to performance of the one or more operations, an initial selection state of the table data via the row and the at least one column for each data table of the plurality of data tables, wherein the initial selection state indicates an association or a lack of an association between the first attribute and the table data stored in the plurality of data tables; and

cause, based on the updated selection state, the handle to be updated by retrieving one or more data values from the table data associated with the one or more changes, wherein the updated handle comprises the updated selection state and indicates, based on the retrieved one or more data values associated with the one or more changes, an association or a lack of an association between the first attribute and the table data.

16. The non-transitory computer-readable storage medium of claim 15 , wherein the updated selection state indicates, for each row of each data table of the plurality of data tables, that data stored in the corresponding row is associated or not associated with the first attribute.

17. The non-transitory computer-readable storage medium of claim 15 , wherein the updated selection state differs at least partially from the initial selection state based on the one or more changes.

18. The non-transitory computer-readable storage medium of claim 15 , wherein the updated selection state comprises an indication of one or more rows of the plurality of data tables that are not indicated by the initial selection state for the first attribute.
