Landscape transformation replication server

1. A computer-readable storage medium containing instructions to configure a processor to perform a method, the method comprising:

providing, by a source system, an initial load of a data item from the source system to a target system, wherein the data item is associated with a database trigger maintained at the source system;

recording, by the source system, a change in a log at the source system, when a change to the data item at the source system causes the trigger to prompt the recording;

extracting, by the source system, the change from the log to enable at least a confirmation of an accuracy of the change;

receiving, at the source system, a call from a replication server; and

providing, in response to the received call, the extracted change to the replication server configured to write the change to the target system.

2. The computer-readable storage medium of claim 1 , wherein the database trigger comprises a database object linked to a table including the data item.

3. The computer-readable storage medium of claim 1 , wherein the providing the initial load further comprises:

writing the data item to a database table at the target system.

4. The computer-readable storage medium of claim 3 , wherein the database table comprises at least one of a plurality of database tables of at least one of an in-memory database and a column-oriented database.

5. The computer-readable storage medium of claim 1 further comprising:

initialing, by the replication server, the initial load of the data item from the source system to the target system, wherein the replication server comprises at least a controller.

6. The computer-readable storage medium of claim 1 , wherein the change comprises at least one of an insert, a create, and a delete.

7. The computer-readable storage medium of claim 1 , wherein the extracting further comprises:

determining the consistency based on a comparison of the log and a table including the data item at the source system.

8. A method comprising:

providing, by a source system, an initial load of a data item from the source system to a target system, wherein the data item is associated with a database trigger maintained at the source system;

recording, by the source system, a change in a log at the source system, when a change to the data item at the source system causes the trigger to prompt the recording;

extracting, by the source system, the change from the log to enable at least a confirmation of an accuracy of the change;

receiving, at the source system, a call from a replication server; and

providing, in response to the received call, the extracted change to the replication server configured to write the change to the target system.

9. The method of claim 8 , wherein the database trigger comprises a database object linked to a table including the data item.

10. The method of claim 8 , wherein the providing the initial load further comprises:

writing the data item to a database table at the target system.

11. The method of claim 10 , wherein the database table comprises at least one of a plurality of database tables of at least one of an in-memory database and a column-oriented database.

12. The method of claim 8 further comprising:

initialing, by the replication server, the initial load of the data item from the source system to the target system, wherein the replication server comprises at least a controller.

13. The method of claim 8 , wherein the change comprises at least one of at least one of an insert, a create, and a delete.

14. The method of claim 8 , wherein the extracting further comprises:

determining the consistency based on a comparison of the log and a table including the data item at the source system.

15. A system comprising:

at least one processor; and

at least one memory including code which when executed by the at least one processor provides operations comprising:

providing, by a source system, an initial load of a data item from the source system to a target system, wherein the data item is associated with a database trigger maintained at the source system;

recording, by the source system, a change in a log at the source system, when a change to the data item at the source system causes the trigger to prompt the recording;

extracting, by the source system, the change from the log to enable at least a confirmation of an accuracy of the change;

receiving, at the source system, a call from a replication server; and

providing, in response to the received call, the extracted change to the replication server configured to write the change to the target system.

16. The system of claim 15 , wherein the database trigger comprises a database object linked to a table including the data item.

17. The system of claim 15 , wherein the providing the initial load further comprises:

writing the data item to a database table at the target system.

18. The system of claim 15 , wherein the database table comprises at least one of a plurality of database tables of at least one of an in-memory database and a column-oriented database.

19. The system of claim 15 further comprising:

initialing, by the replication server, the initial load of the data item from the source system to the target system, wherein the replication server comprises at least a controller.

20. The system of claim 15 , wherein the change comprises at least one of at least one of an insert, a create, and a delete.
