Abstract

The present disclosure describes methods, systems, and computer program products for performing integration logic programming. One computer-implemented method includes receiving, by operation of a middleware system, first information in a first format corresponding to a first application, applying, by operation of the middleware system, one or more integration logic programming (ILP) patterns to the first information, the one or more ILP patterns representing application integration semantics using a logic programming language, generating, by operation of the middleware system, a second information in response to applying the one or more ILP patterns to the first information, and outputting, by operation of the middleware system, the second information in a second format corresponding to a second application.

First claim

What is claimed is:

1. A computer-implemented method comprising:
receiving, by operation of a middleware system, first information in a first format corresponding to a first application, wherein the middleware system comprises a set of protocol adapters for receiving information corresponding to a plurality of applications through a plurality of protocols, the information being in a plurality of different formats;
converting the first information in the first format into converted first information with a canonical data model format;
applying, by operation of the middleware system, a plurality of integration logic programming (ILP) patterns to the converted first information, the plurality of ILP patterns representing application integration semantics using a logic programming language, wherein one of the plurality of ILP patterns comprises a message filter, configured to route the converted first information based on a set of facts within the converted first information;
generating, by operation of the middleware system, a reduced set of intermediate results as aggregated information in response to applying a first ILP pattern of the plurality of ILP patterns to the first information and a second ILP pattern of the plurality of ILP patterns to second information corresponding to a second application to generate the intermediate results, wherein the first application and the second application run on different systems and use different database solutions, computer languages, or data formats; and
outputting, by operation of the middleware system, the aggregated information in a target format corresponding to a target application.

2. The method of claim 1 , wherein the first ILP pattern of the plurality of ILP patterns comprises DATALOG or PROLOG.

3. The method of claim 1 , wherein one of the plurality of ILP patterns comprises a content filter configured to remove a portion of the converted first information before routing the converted first information.

4. The method of claim 1 , comprising defining the plurality of ILP patterns by representing application integration semantics using the logic programming language.

5. The method of claim 1 , wherein applying the first ILP pattern of the plurality of ILP patterns to the first information comprises applying a composited ILP pattern to allow extended logic programming processing, the composited ILP pattern comprises two or more ILP patterns.

6. The method of claim 1 , wherein the first format is Extensible Markup Language (XML), JAVASCRIPT Object Notation (JSON), Java, or C#, and the canonical data model format is DATALOG, PROLOG, or Structured Query Language (SQL).

7. A non-transitory, computer-readable medium storing computer-readable instructions executable by a computer and configured to:
receive, by operation of a middleware system, first information in a first format corresponding to a first application, wherein the middleware system comprises a set of protocol adapters for receiving information corresponding to a plurality of applications through a plurality of protocols, the information being in a plurality of different formats;
convert the first information in the first format into converted first information with a canonical data model format;
apply a plurality of integration logic programming (ILP) patterns to the converted first information, the plurality of ILP patterns representing application integration semantics using a logic programming language, wherein one of the plurality of ILP patterns comprises a message filter, configured to route the converted first information based on a set of facts within the converted first information;
generate a reduced set of intermediate results as aggregated information in response to applying a first ILP pattern of the plurality of ILP patterns to the first information and a second ILP pattern of the plurality of ILP patterns to second information corresponding to a second application to generate the intermediate results, wherein the first application and the second application run on different systems and use different database solutions, computer languages, or data formats; and
output the aggregated information in a target format corresponding to a target application.

8. The non-transitory, computer-readable medium of claim 7 , wherein the first ILP pattern of the plurality of ILP patterns comprises DATALOG or PROLOG.

9. The non-transitory, computer-readable medium of claim 7 , wherein one of the plurality of ILP patterns comprises a content filter configured to remove a portion of the converted first information before routing the converted first information.

10. The non-transitory, computer-readable medium of claim 7 , comprising instructions to define the plurality of ILP patterns by representing application integration semantics using the logic programming language.

11. The non-transitory, computer-readable medium of claim 7 , wherein applying the first ILP pattern of the plurality of ILP patterns to the first information comprises applying a composited ILP pattern to allow extended logic programming processing, the composited ILP pattern comprises two or more ILP patterns.

12. The non-transitory, computer-readable medium of claim 7 , wherein the first format is Extensible Markup Language (XML), JAVASCRIPT Object Notation (JSON), Java, or C#, and the canonical data model format is DATALOG, PROLOG, or Structured Query Language (SQL).

13. A system, comprising:
a memory;
at least one hardware processor interoperably coupled with the memory and configured to:
receive, by operation of a middleware system, first information in a first format corresponding to a first application, wherein the middleware system comprises a set of protocol adapters for receiving information corresponding to a plurality of applications through a plurality of protocols, the information being in a plurality of different formats;
convert the first information in the first format into converted first information with a canonical data model format;
apply a plurality of integration logic programming (ILP) patterns to the converted first information, the plurality of ILP patterns representing application integration semantics using a logic programming language, wherein one of the plurality of ILP patterns comprises a message filter, configured to route the converted first information based on a set of facts within the converted first information;
generate a reduced set of intermediate results as aggregated information in response to applying a first ILP pattern of the plurality of ILP patterns to the first information and a second ILP pattern of the plurality of ILP patterns to second information corresponding to a second application to generate the intermediate results, wherein the first application and the second application run on different systems and use different database solutions, computer languages, or data formats; and
output the aggregated information in a target format corresponding to a target application.

14. The system of claim 13 , wherein the first ILP pattern of the plurality of ILP patterns comprises DATALOG or PROLOG.

15. The system of claim 13 , wherein one of the plurality of ILP patterns comprises a content filter configured to remove a portion of the converted first information before routing the converted first information.

16. The system of claim 13 , wherein applying the first ILP pattern of the plurality of ILP patterns to the first information comprises applying a composited ILP pattern to allow extended logic programming processing, the composited ILP pattern comprises two or more ILP patt
