Abstract

A system and method for object system interoperability is provided. The system comprises an object generator, a target program, and a formatter which is a serializer and/or deserializer. The method comprises the steps of executing the object generator, which uses a data model specification to generate self-reflective object classes in the target program, which in turn calls a formatter to translate between an object instance and serial data.

Claims

1. A method comprising:

providing a data model specification to an object generator;

executing the object generator to generate code comprising a DMS object class with at least one self-reflection function; and

executing a program which in turn executes a formatter which is separate from the object class, whereby the formatter translates between at least one DMS object instance and at least one DMS serial data package.

2. A method according to claim 1, wherein the formatter comprises a serializer.

3. A method according to claim 1, wherein the formatter comprises a deserializer.

4. A method according to claims 1, wherein the formatter comprises:

a serializer; and

a deserializer, and wherein the serializer and deserializer are separate formatters.

5. A method according to claims 1, wherein the formatter comprises:

a serializer; and

a deserializer, and wherein the serializer and deserializer are a single formatter.

6. A method according to claim 1, wherein executing the program comprises creating from the object class an object instance;

and executing the formatter to serialize the DMS object instance into the DMS serial data package, using information from the self-reflection function of the DMS object class.

7. A method according to claim 1, wherein executing the program comprises executing the formatter to deserialize the DMS serial data package into the DMS object instance, using information from the self-reflection function of the DMS object class.

8. A method according to claim 1, wherein the self-reflection function describes to the formatter the name(s), data type(s), value(s), and relation(s) of an object instance.

9. A method according to claim 1, wherein the DMS serial data package is in a data interchange format.

10. A method according to claim 1, wherein the data interchange format is XML.

11. A method according to claim 1, wherein the data interchange format is Tibco Rendezvous.

12. A method according to claim 1, wherein the data interchange format is CSV.

13. A method according to claim 1, wherein the model specification is an XML Schema.

14. A method according to claim 1, wherein the model specification is a DTD.

15. A method according to claim 1, wherein the model specification is a DDL.

16. A method according to claim 1, wherein at least a majority of the program is written in Java.

17. A method according to claim 1, wherein at least a majority of the program is written in C++.

18. A method according to claim 1, wherein at least a majority of the program is written in Visual Basic.

19. A method according to claim 1, wherein at least a majority of the program is written in Smalltalk.

20. A method according to claim 1, wherein the DMS object class contains domain syntax.

21. A method according to claim 1, wherein the DMS serial data package contains domain syntax.

22. A method according to claim 1, further comprising a validation step.

23. A method according to claim 1, wherein the validation comprises structural validation.

24. A method according to claim 1, wherein the validation comprises content validation.

25. A method according to claim 1, wherein the validation comprises structural and content validation.

26. A method according to claim 1, wherein the validation is decoupled from translation.

27. A method according to claim 1, wherein the validation is performed before the translation.

28. A method according to claim 1, wherein the validation is performed after the translation.

29. A method comprising:

a step for providing a data model specification to an object generator;

a step for executing the object generator to generate code comprising a DMS object class with at least one self-reflection function; and

a step for executing a program which in turn executes a formatter which is separate from the object class, whereby the formatter translates between at least one DMS object instance and at least one DMS serial data package.

30. An apparatus comprising:

means for providing a data model specification to an object generator;

means for executing the object generator to generate code comprising a DMS object class with at least one self-reflection function; and

means for executing a program which in turn executes a formatter which is separate from the object class, whereby the formatter translates between at least one DMS object instance and at least one DMS serial data package.

31. A system comprising:

an object-oriented program;

an object generator capable of using a data model specification to generate code comprising a DMS object class with at least one self-reflection function;

a DMS object class created by the object generator; and

a formatter which is separate from the DMS object class and is capable of using information from the self-reflection function to translate between a DMS object instance and a DMS serial data package.

32. Computer executable software code comprising:

code comprising a data model specification;

code to use the data model specification to generate code comprising a DMS object class with at least one self-reflection function;

code comprising the DMS object class; and

code to separate from the DMS object class to translate between a DMS object instance and a DMS serial data package, using information from the self-reflection function.

33. A programmed computer comprising:

a memory having at least one region for storing code; and

a processor for executing code stored in the memory;

wherein

the memory is programmed with code comprising a data model specification;

the processor is programmed to use the data model specification to generate code comprising a DMS object class with at least one self-reflection function;

the memory is programmed with code comprising the DMS object class; and

the processor is programmed to separate from the DMS object class to translate between a DMS object instance and a DMS serial data package, using information from the self-reflection function.
