Abstract

A mesh structure can be a type concept that extends internal tables or other data structures of a business programming languages (e.g., ABAP) by associations, as known from a data object meta-model. A mesh can include a set of operations, such as for example iteration via an iterator object and selection of instances expressed by a path language. A mesh structure can be optimized for read access and traversal, and can provide a working area that is processed with statements in the business programming language to implement one or more core services directly from the mesh data structure. Related methods, computer program products, and systems are described.

First claim

What is claimed is:

1. A computer program product comprising a non-transitory machine-readable medium storing instructions that, when executed by a system comprising at least one programmable processor, cause the system to perform operations comprising:
storing, in a mesh structure comprising a single data object implemented natively within a business programming language, semantically grouped data from a plurality of nodes of two or more business objects;
providing, via the mesh structure, a working area that is processed with statements in the business programming language to implement one or more core services directly from the mesh structure;
supporting links between two or more nodes of the plurality of nodes via coded path expressions that are included in a definition of the mesh structure; and
allowing retrieval, from a relational database underlying the two or more business objects, of data from the plurality of nodes of the two or more business objects via the mesh structure.

2. A computer program product as in claim 1 , wherein the business programming language comprises ABAP, the Advanced Business Programming Language.

3. A computer program product as in claim 1 , wherein the mesh structure stores the semantically grouped data in application memory during runtime.

4. A computer program product as in claim 1 , wherein the one or more core services are implemented directly at a mesh level of the mesh structure without requiring an additional processing framework coded on top of the mesh structure.

5. A computer program product as in claim 1 , wherein the one or more core services comprise an iterator function.

6. A computer program product as in claim 1 , wherein the one or more core services comprise a selector function.

7. A system comprising:
at least one programmable processor; and
a machine-readable medium storing instructions that, when executed by the at least one processor, cause the at least one programmable processor to perform operations comprising:
storing, in a mesh structure comprising a single data object implemented natively within a business programming language, semantically grouped data from a plurality of nodes of two or more business objects;
providing, via the mesh structure, a working area that is processed with statements in the business programming language to implement one or more core services directly from the mesh structure;
supporting links between two or more nodes of the plurality of nodes via coded path expressions that are included in a definition of the mesh structure; and
allowing retrieval, from a relational database underlying the two or more business objects, of data from the plurality of nodes of the two or more business objects via the mesh structure.

8. A system as in claim 7 , wherein the business programming language comprises ABAP, the Advanced Business Programming Language.

9. A system as in claim 7 , wherein the mesh structure stores the semantically grouped data in application memory during runtime.

10. A system as in claim 7 , wherein the one or more core services are implemented directly at a mesh level of the mesh structure without requiring an additional processing framework coded on top of the mesh structure.

11. A system as in claim 7 , wherein the one or more core services comprise an iterator function.

12. A system as in claim 7 , wherein the one or more core services comprise a selector function.

13. A computer-implemented method comprising:
storing, in a mesh structure comprising a single data object implemented natively within a business programming language, semantically grouped data from a plurality of nodes of two or more business objects;
providing, via the mesh structure, a working area that is processed with statements in the business programming language to implement one or more core services directly from the mesh structure;
supporting links between two or more nodes of the plurality of nodes via coded path expressions that are included in a definition of the mesh structure; and
allowing retrieval, from a relational database underlying the two or more business objects, of data from the plurality of nodes of the two or more business objects via the mesh structure.

14. A computer-implemented method as in claim 13 , wherein the business programming language comprises ABAP, the Advanced Business Programming Language.

15. A computer-implemented method as in claim 13 , wherein the mesh structure stores the semantically grouped data in application memory during runtime.

16. A computer-implemented method as in claim 13 , wherein the one or more core services are implemented directly at a mesh level of the mesh structure without requiring an additional processing framework coded on top of the mesh structure.

17. A computer-implemented method as in claim 13 , wherein the one or more core services comprise an iterator function.

18. A computer-implemented method as in claim 13 , wherein the one or more core services comprise a selector function.

19. A computer-implemented method as in claim 13 , wherein at least one of the storing, the providing, the supporting, and the allowing is performed by a system comprising at least one programmable processor.
