Abstract

A system and method for automatic instance data mapping generation is presented. A developer uses edit commands, such as mouse commands and keyboard commands, to update a model. For example, a software developer may upgrade “Application XYZ” from version 1.0 to version 2.0 in order to include a simpler approach to import images, as well as the ability to import newer image format types. As a developer updates a model using edit commands, the edit commands are stored in a migration mapping definition. In turn, the migration mapping definition is deployed, along with the updated model, to an end user. The end user then uses the migration mapping definition to migrate instance data generated by the original model to instance data that is usable by the updated model.

Claims

1. A computer-implemented method comprising:

receiving an edit command that corresponds to an original model;

updating the original model using the edit command, the updating resulting in an updated model;

storing the edit command into a migration mapping definition, the migration mapping definition adapted to migrate original instance data corresponding to the original model to migrated instance data that corresponds to the updated model; and

deploying the migration mapping definition and the updated model to an end user.

2. The method of claim 1 wherein the deploying results in the migration mapping definition and the updated model being stored on a computer system corresponding to the end user, the method further comprising:

receiving, at the end user'"'"'s computer system, an instance data migration request from the end user;

retrieving the original instance data located at the end user'"'"'s computer system;

loading the migration mapping definition into a migration engine located at the end user'"'"'s computer system;

converting the original instance data to the migrated instance data using the migration engine and the migration mapping definition at the end user'"'"'s computer system; and

displaying the migrated instance data using the updated model at the end user'"'"'s computer system.

3. The method of claim 2 wherein the converting further comprises:

identifying a first element in the original instance data;

determining that the first element is included in the migration mapping definition;

locating, in response to the determination, a transformer based upon the migration mapping definition; and

generating the migrated instance data using the transformer.

4. The method of claim 3 further comprising:

identifying a second element in the original instance data;

determining that the second element is not included in the migration mapping definition; and

copying data corresponding to the second element to the migrated instance data in response to determining that the second element is not included in the migration mapping definition.

5. The method of claim 2 wherein the converting and the displaying are performed using a model-driven framework.

6. The method of claim 1 further comprising:

receiving one or more changes from a developer in response to the developer verifying the migration mapping definition; and

including the one or more changes in the migration mapping definition.

7. The method of claim 1 wherein the original model is a first version of a computer program and the updated model is a second version of the computer program.

8. A computer program product stored on a computer operable media, the computer operable media containing instructions for execution by a computer, which, when executed by the computer, cause the computer to implement a method for automatic instance data mapping generation, the method comprising:

receiving an edit command that corresponds to an original model;

updating the original model using the edit command, the updating resulting in an updated model;

storing the edit command into a migration mapping definition, the migration mapping definition adapted to migrate original instance data corresponding to the original model to migrated instance data that corresponds to the updated model; and

deploying the migration mapping definition and the updated model to an end user.

9. The computer program of claim 8 wherein the deploying results in the migration mapping definition and the updated model being stored on a computer system corresponding to the end user, the method further comprising:

receiving, at the end user'"'"'s computer system, an instance data migration request from the end user;

retrieving the original instance data located at the end user'"'"'s computer system;

loading the migration mapping definition into a migration engine located at the end user'"'"'s computer system;

converting the original instance data to the migrated instance data using the migration engine and the migration mapping definition at the end user'"'"'s computer system; and

displaying the migrated instance data using the updated model at the end user'"'"'s computer system.

10. The computer program of claim 9 wherein the method further comprises:

identifying a first element in the original instance data;

determining that the first element is included in the migration mapping definition;

locating, in response to the determination, a transformer based upon the migration mapping definition; and

generating the migrated instance data using the transformer.

11. The computer program of claim 10 wherein the method further comprises:

identifying a second element in the original instance data;

determining that the second element is not included in the migration mapping definition; and

copying data corresponding to the second element to the migrated instance data in response to determining that the second element is not included in the migration mapping definition.

12. The computer program of claim 8 wherein the converting and the displaying are performed using a model-driven framework.

13. The computer program of claim 10 wherein the method further comprises:

receiving one or more changes from a developer in response to the developer verifying the migration mapping definition; and

including the one or more changes in the migration mapping definition.

14. The computer program of claim 8 wherein the original model is a first version of a computer program and the updated model is a second version of the computer program.
