Efficient support for automatic generation of a partially-editable dataset copy

1. A computer-implemented method comprising:

receiving an edit request from a user to edit a data set;

determining, based on a context of the edit request, a first filter for the data set that defines an editable portion of the data set, wherein the context of the edit request comprises preconfigured data locking permissions;

identifying a non-editable portion of the data set using a negated filter that is a negation of the first filter;

using the first filter to generate a partially-editable copy of the data set that includes the editable portion of the data set;

generating an exposed view of the data set that exposes the partially-editable copy of the data set and the non-editable portion of the data set;

providing the exposed view of the data set to the user;

receiving, in the exposed view, a change to a first data item in the editable portion of the data set; and

updating the first data item in the partially-editable copy of the data set based on the change to the first data item.

2. The computer-implemented method of claim 1 , wherein the context of the edit request specifies at least one dimension of the data set.

3. The computer-implemented method of claim 2 , wherein the context of the edit request includes a role of the user.

4. The computer-implemented method of claim 3 , wherein the role determines preconfigured data access permissions for the user.

5. The computer-implemented method of claim 4 , wherein determining the first filter for the data set comprises determining, based on the preconfigured data access permissions, for which dimension values the user has write access.

6. The computer-implemented method of claim 1 , wherein determining the first filter for the data set comprises determining, based on preconfigured the data locking permissions, which dimension values are unlocked.

7. The computer-implemented method of claim 1 , wherein using the first filter to generate the partially-editable copy of the data set comprises copying, into the partially-editable copy of the data set, portions of the data set that match the first filter.

8. The computer-implemented method of claim 1 , wherein updating the first data item in the partially-editable copy of the data set comprises determining that the first data item matches the first filter.

9. The computer-implemented method of claim 1 , further comprising:

receiving a change to a second data item that is included in the non-editable portion;

determining that the second data item does not match the first filter; and

rejecting the change to the second data item based on determining that the second data item does not match the first filter.

10. The computer-implemented method of claim 1 , further comprising improving the first filter by adjusting the first filter based on a performance analysis.

11. A system comprising:

one or more computers; and

a computer-readable medium coupled to the one or more computers having instructions stored thereon which, when executed by the one or more computers, cause the one or more computers to perform operations comprising:

receiving an edit request from a user to edit a data set;

determining, based on a context of the edit request, a first filter for the data set that defines an editable portion of the data set, wherein the context of the edit request comprises preconfigured data locking permissions;

identifying a non-editable portion of the data set using a negated filter that is a negation of the first filter;

using the first filter to generate a partially-editable copy of the data set that includes the editable portion of the data set;

generating an exposed view of the data set that exposes the partially-editable copy of the data set and the non-editable portion of the data set;

providing the exposed view of the data set to the user;

receiving, in the exposed view, a change to a first data item in the editable portion of the data set; and

updating the first data item in the partially-editable copy of the data set based on the change to the first data item.

12. The system of claim 11 , wherein the context of the edit request specifies at least one dimension of the data set.

13. The system of claim 12 , wherein the context of the edit request includes a role of the user.

14. The system of claim 13 , wherein the role determines preconfigured data access permissions for the user.

15. A computer program product encoded on a non-transitory storage medium, the product comprising non-transitory, computer readable instructions for causing one or more processors to perform operations comprising:

receiving an edit request from a user to edit a data set;

determining, based on a context of the edit request, a first filter for the data set that defines an editable portion of the data set, wherein the context of the edit request comprises preconfigured data locking permissions;

identifying a non-editable portion of the data set using a negated filter that is a negation of the first filter;

using the first filter to generate a partially-editable copy of the data set that includes the editable portion of the data set;

generating an exposed view of the data set that exposes the partially-editable copy of the data set and the non-editable portion of the data set;

providing the exposed view of the data set to the user;

receiving, in the exposed view, a change to a first data item in the editable portion of the data set; and

updating the first data item in the partially-editable copy of the data set based on the change to the first data item.

16. The computer program product of claim 15 , wherein the context of the edit request specifies at least one dimension of the data set.

17. The computer program product of claim 16 , wherein the context of the edit request includes a role of the user.

18. The computer program product of claim 17 , wherein the role determines preconfigured data access permissions for the user.
