Abstract

A virtual item set representing a subset of items stored within an original data structure. The system includes a virtual item set processor configured to generate a plurality of virtual items that are a subset of items in the original data structure, and a virtual item set including the plurality of virtual items. Each virtual item includes a data field containing a data item from the original data structure and a metadata field, the meta field data including position information representing the position of the data field within an original data structure.

Claims

1. A computer-implemented system for providing a representation of a subset of items stored within an original data structure, comprising:

a computer-readable medium having computer-executable instructions stored thereon, the computer-executable instructions being executed by a processor to implement

a virtual item set processor configured to generate a virtual item set containing a plurality of virtual items, wherein the plurality of virtual items includes the subset of items in the original data structure, wherein each virtual item of the plurality of virtual items includes

a data field containing a reference to a data item in the original data structure, wherein the reference includes position information representing a position of the data item within the original data structure, and

a metadata field, wherein the metadata field contains information regarding characteristics of the data item to which the data field refers;

wherein the virtual item set processor is configured to receive a change to the data field, wherein the virtual item set processor is configured to change the data item in response to the received change to the data field, wherein the virtual item set processor is configured to change the data item directly in the original data structure using the reference.

2. The system of claim 1, wherein the virtual item set is at least one of a sorted table, a non-sorted table, and a hash table.

3. The system of claim 1, wherein the metadata field includes a name, a data type, a unique identifier, a parent identifier, a child identifier, and a data field type.

4. The system of claim 1, wherein the original data structure is a deep data structure.

5. The system of claim 1, wherein the virtual item set processor is further configured to perform at least one mass data processing operation.

6. The system of claim 1, wherein the data field is at least one of a value, a data structure and a table.

7. The system of claim 1, wherein the items stored within the original data structure represent articles for sale in a retail setting, wherein the metadata includes at least one of a description, color, price, and markdown of an article represented by an item.

8. The system of claim 1, wherein the virtual item set processor is configured to generate the virtual item set by performing at least one of selecting items used for a task and selecting recently accessed items.

9. A computer-implemented method for providing a representation of a subset of items within an original data structure, comprising:

generating, using a processing engine, a virtual item set containing a plurality of virtual items, wherein the processing engine is implemented using computer-executable instructions executable by a processor and stored on a computer-readable medium, wherein the plurality of virtual items includes the subset of items in the original data structure, wherein each virtual item includes

a data field containing a reference to a data item in the original data structure, wherein the reference includes position information representing a position of the data item within the original data structure, and

a metadata field, wherein the metadata field contains information regarding characteristics of the data item to which the data field refers;

receiving a change to the data field; and

changing, using the processing engine, the data item in response to the received change to the data field, wherein the data item is changed directly in the original data structure using the reference.

10. The method of claim 9, wherein the virtual item set is at least one of a sorted table, a non-sorted table, and a hash table.

11. The method of claim 9, wherein the metadata field includes a name, a data type, a unique identifier, a parent identifier, a child identifier, and a data field type.

12. The method of claim 9, wherein the original data structure is a deep data structure.

13. The method of claim 9, wherein the data field is at least one of a value, a data structure and a table.

14. A computer-readable medium having computer-executable instructions stored thereon, wherein the computer-executable instructions are executable by a processor to implement a method for representing a subset of items from an original data structure, the method comprising:

generating, using a processing engine, a virtual item set containing a plurality of virtual items, wherein the plurality of virtual items includes the subset of items in the original data structure, wherein each virtual item includes

a data field containing a reference to a data item in the original data Strcture, and

a metadata field, wherein the metadata field contains information regarding characteristics of the data item to which the data field refers;

receiving a change to the data field; and

changing, using the processing engine, the data item in response to the received change to the data field, wherein the data item is changed directly in the original data structure using the reference.

15. The computer-readable medium of claim 14, wherein the virtual item set is at least one of a sorted table, a non-sorted table, and a hash table.

16. The computer-readable medium of claim 14, wherein the metadata field further includes a name, a data type, a unique identifier, a parent identifier, a child identifier, and a data field type.

17. The computer-readable medium of claim 14, wherein the original data structure is a deep data structure.
