determine a user permission associated with the data in the location of the hypercube using the user permission list, wherein determining the user permission is based at least in part on whether a node associated with the location in the hypercube is pruned from a tree rooted at the root node;

provide an indication of the user permission; and

receive an access region comprising a set of access region dimension values, an access region user or set of users, and an access region permission;

modify a tree structure of dimension values to allow description of the set of access region dimension values using the root node and the set of pruned nodes;

7. The system of claim 2 , wherein, in response to determining that the user permission comprises read with no splits permission, providing the data in the location in the hypercube to the user according to the user permission comprises allowing the user to access information by reading the location but not allowing reading a transaction information.

8. The system of claim 2 , wherein, in response to determining that the user permission comprises no permission, providing the data in the location in the hypercube to the user according to the user permission comprises providing no access to the data in the location in the hypercube to the user.

9. The system of claim 1 , wherein determining the user permission comprises:

selecting a node associated with the location of the data in the hypercube,

determining that the selected node is descendent from the root node of the element; and

determining that the selected node is not descendent from a pruned node of the set of pruned nodes.

10. The system of claim 1 , wherein determining a user permission comprises generating a sorted user permission list by sorting the user permission list.

11. The system of claim 10 , wherein the sorted user permission list is sorted from most to least permissive permission associated with a first element, wherein for the first element of the sorted user permission list that the user is determined to have permission, assigning the permission of the element to the location of the data in the hypercube.

12. The system of claim 10 , wherein the sorted user permission list is sorted from least to most permissive permission associated with a first element, wherein for the first element of the sorted user permission list that the user is determined to have permission, assigning the permission of the element to the location of the data in the hypercube.

13. The system of claim 1 , wherein the permission comprises one of: write permission, import and notes permission, read except notes permission, read permission, read with no splits permission, or no permission.

14. The system of claim 1 , wherein the element of the user permission list further comprises a dimension associated with the element.

15. The system of claim 1 , wherein the user permission list comprises a subset of a global permission list comprising entries of the global permission list associated with the user.

16. The system of claim 1 , wherein modifying the tree structure of dimension values to allow description of the set of access region dimension values using the root node and the set of pruned nodes comprises adding a new node to the tree structure corresponding to the set of access region dimension values.

17. The system of claim 1 , wherein modifying the tree structure of dimension values to allow description of the set of dimension values using the root node and the set of pruned nodes comprises adding a new subtree to the tree structure corresponding to the set of access region dimension values.

18. The system of claim 1 , wherein modifying the tree structure of dimension values to allow description of the set of access region dimension values using the root node and the set of pruned nodes comprises adding a new node to the tree structure corresponding to the pruned set of dimension values for pruning.

19. The system of claim 18 , wherein a subtree rooted at an ancestor node comprising an ancestor of the new node, wherein the new node is pruned from the subtree, corresponds to the set of access region dimension values.

20. A method for determining access for a hypercube, comprising:

receiving a request for access from a user to data in a location in a hypercube;

receiving a tree structure with subcubes of the hypercube arranged in a hierarchical structure;

receiving a user permission list, wherein an element of the user permission list comprises a permission, a root node, and a set of pruned nodes, wherein the permission does not apply to the set of pruned nodes;

determining, using a hardware processor, a user permission associated with the data in the location of the hypercube using the user permission list, wherein determining the user permission is based at least in part on whether a node associated with the location in the hypercube is pruned from a tree rooted at the root node;

providing an indication of the user permission; and

receiving an access region comprising a set of access region dimension values, an access region user or set of users, and an access region permission;
