Automated development, deployment and integration service for distributed ledger-enabled applications

1. A computer-implemented method for enabling an application for use with a distributed ledger system (DLS), the method being executed by one or more processors and comprising:

providing a DLS-enriched view on data stored in a database system, the DLS-enriched view comprising a set of annotations indicating at least one application table and at least one field of the application table that is DLS-enabled, the data being stored in the database system based on a DLS-enriched data model provided from a pre-enriched data model;

storing, in the database system, a staging table corresponding to the at least one application table and the at least one field of the at least one application table and a database trigger that is configured to write data from the at least one field of the at least one application table to the staging table in response to a change in the at least one application table, the staging table and the database trigger being created in response to the DLS-enriched data model, the DLS-enriched data model mapping the at least one application table to the staging table;

during a design-time:

providing at least one intermediate representative (IR) artifact based on the DLS-enriched view, and

generating at least one DLS-specific entity and chaincode based on the at least one IR artifact and a configuration for the DLS, to which the chaincode is to be deployed;

during a deployment-time, deploying the chaincode to the DLS; and

during a run time, monitoring the staging table for changes and, in response to a change: recording data of the staging table to the DLS based on the chaincode, and automatically writing to the staging table using the database trigger.

2. The method of claim 1 , wherein the set of annotations comprises a DLS-enable annotation and a DLS attribute annotation, the DLS attribute annotation indicating the at least one field.

3. The method of claim 1 , wherein the IR artifact is DLS-agnostic.

4. The method of claim 1 , wherein the chaincode is a DLS-enabled application that is specific to the DLS and comprises at least a portion of functionality of the application.

5. The method of claim 1 , wherein the application selectively writes data to the at least one field.

6. The method of claim 1 , wherein the at least one DLS-specific entity is specific to the DLS.

7. The method of claim 1 , further comprising deleting the data from the staging table in response to confirmation that the data has been recorded to the DLS.

8. A non-transitory computer-readable storage medium coupled to one or more processors and having instructions stored thereon which, when executed by the one or more processors, cause the one or more processors to perform operations for enabling an application for use with a distributed ledger system (DLS), the operations comprising:

providing a DLS-enriched view on data stored in a database system, the DLS-enriched view comprising a set of annotations indicating at least one application table and at least one field of the application table that is DLS-enabled, the data being stored in the database system based on a DLS-enriched data model provided from a pre-enriched data model;

storing, in the database system, a staging table corresponding to the at least one application table and the at least one field of the at least one application table and a database trigger that is configured to write data from the at least one field of the at least one application table to the staging table in response to a change in the at least one application table, the staging table and the database trigger being created in response to the DLS-enriched data model, the DLS-enriched data model mapping the at least one application table to the staging table;

during a design-time:

providing at least one intermediate representative (IR) artifact based on the DLS-enriched view, and

generating at least one DLS-specific entity and chaincode based on the at least one IR artifact and a configuration for the DLS, to which the chaincode is to be deployed;

during a deployment-time, deploying the chaincode to the DLS; and

during a run time, monitoring the staging table for changes and, in response to a change: recording data of the staging table to the DLS based on the chaincode, and automatically writing to the staging table using the database trigger.

9. The computer-readable storage medium of claim 8 , wherein the set of annotations comprises a DLS-enable annotation and a DLS attribute annotation, the DLS attribute annotation indicating the at least one field.

10. The computer-readable storage medium of claim 8 , wherein the IR artifact is DLS-agnostic.

11. The computer-readable storage medium of claim 8 , wherein the chaincode is a DLS-enabled application that is specific to the DLS and comprises at least a portion of functionality of the application.

12. The computer-readable storage medium of claim 8 , wherein the application selectively writes data to the at least one field.

13. The computer-readable storage medium of claim 8 , wherein the at least one DLS-specific entity is specific to the DLS.

14. The computer-readable storage medium of claim 8 , wherein operations further comprise deleting the data from the staging table in response to confirmation that the data has been recorded to the DLS.

15. A system, comprising:

a computing device; and

a computer-readable storage device coupled to the computing device and having instructions stored thereon which, when executed by the computing device, cause the computing device to perform operations for enabling an application for use with a distributed ledger system (DLS), the operations comprising:

providing a DLS-enriched view on data stored in a database system, the DLS-enriched view comprising a set of annotations indicating at least one application table and at least one field of the application table that is DLS-enabled, the data being stored in the database system based on a DLS-enriched data model provided from a pre-enriched data model;

storing, in the database system, a staging table corresponding to the at least one application table and the at least one field of the at least one application table and a database trigger that is configured to write data from the at least one field of the at least one application table to the staging table in response to a change in the at least one application table, the staging table and the database trigger being created in response to the DLS-enriched data model, the DLS-enriched data model mapping the at least one application table to the staging table;

during a design-time:

providing at least one intermediate representative (IR) artifact based on the DLS-enriched view, and

generating at least one DLS-specific entity and chaincode based on the at least one IR artifact and a configuration for the DLS, to which the chaincode is to be deployed;
