Abstract

A system and method for projecting the transformation of object trees, especially in MES systems, wherein the course object tree and target object tree are represented in a common meta-object model of a software system, especially a framework. The source object tree is transformed into the target object tree by adjustment. Transformation occurs directly in the object of the meta-object model, thereby enabling communication between connected applications by means of pure data exchange.

Claims

1-17. -17. (canceled)

18. A system for projecting transformations of object trees, wherein the source and target object trees are represented in a common meta-object model of a software system and wherein the software system is stored on at least one computer unit, the system for projecting comprising:

a first screen area of a display device for representing a source object tree;

a second screen area of the display device for representing a target object tree;

a third screen area of the display device for representing a work area for positioning the nodes of the object trees; and

a fourth screen area of the display device for representing operators and/or rules, wherein the operators and/or rules can be positioned on the work area, and wherein

projecting a transformation on the work area is accomplished by connecting symbols positioned on the work area.

19. A system according to claim 18, wherein the transformation is performed in the user domain.

20. A system according to claim 18, wherein the rules are represented as objects of the software system.

21. A system according to claim 18, wherein the nodes and/or the operators and/or the rules are positioned and interconnected by input aids using drag&

drop.

22. A system according to claim 18, wherein further transformation operators and/or rules are defined by a user.

23. A system according to claim 18, wherein the software system is implemented by at least one framework program.

24. A system according to claim 18, wherein the source object tree and the target object tree are predefined by the object models of coupled adapters.

25. A method for projecting transformations of object trees, comprising:

representing the source object tree and target object tree in a common meta-object model of a software system;

storing the software system on at least one computer unit;

displaying a source object tree on a first screen area of a display device;

displaying a target object tree on a second screen area of the display device;

providing a work area on a third screen area of the display device;

positioning nodes of the object trees on the work area; and

projecting a transformation on the work area by connection symbols positioned on the work area.

26. The method according to claim 25, further comprising:

displaying operators and/or rules on a fourth screen area of the display device; and

positioning the operators and/or the rules on the work area.

27. The method according to claim 25, wherein the transformation is performed in the underlying user domain.

28. The method according to claim 26, wherein the rules are represented as objects of the software system.

29. The method according to claim 25, wherein the nodes are positioned and interconnected by input aids using drag&

drop.

30. The method according to claim 26, wherein the operators and/or the rules are positioned and interconnected by input aids using drag&

drop.

31. The method according to claim 25, wherein further transformation operators and/or rules are defined by a user.

32. The method according to claim 25, wherein the software system is implemented by at least one framework program.

33. The method according to claim 25, wherein the source and target object tree are predefined by the object models of coupled adapters.

34. The method according to claim 25, wherein the method is implemented by a computer program.

35. The method according to claim 25, wherein the method is implemented by a computer program which is stored on a data medium.

36. A data processing device comprising a computer program for performing a method for projecting transformations of object trees, the method comprising:

representing the source object tree and target object tree in a common meta-object model of a software system;

storing the software system on at least one computer unit;

displaying a source object tree on a first screen area of a display device;

displaying a target object tree on a second screen area of the display device;

providing a work area on a third screen area of the display device;

positioning nodes of the object trees on the work area; and

projecting a transformation on the work area by connection symbols positioned on the work area.
