Generic data staging and loading using enhanced metadata and associated method

1. A system to reduce data loading time from one or more source systems, minimize any effect on the one or more source systems during data loading, and correct any error in the data, comprising:

a master data management computer system comprising a processor and a memory, the master database management computer system configured to:

invoke batch data loading of batch data of one or more source systems into an unconstrained area of an input staging area;

automatically select one or more staging and master interfaces based on metadata of the one or more source systems;

automatically select relational table structures based on semantic mapping metadata;

evaluate the batch data loaded into the input staging area by an error correction workflow, wherein the error correction workflow comprises a structured query language implemented as a stored procedure;

move any error records into an error table;

correct any error records in the error table by a spooler within the error correction workflow, wherein the spooler invokes a data upload service which serializes data in XML format and invokes an application programming interface;

load the batch data from the input staging area and corrected data from the error table into a master repository; and

load the batch data from the master repository into an output staging area.

2. The system of claim 1 , wherein the computer is further configured to:

provide an event node comprising a persist net change node, wherein the error correction workflow waits on the persist net change node until an upload process is complete.

3. The system of claim 1 , wherein the computer is further configured to:

issue a callback by a data upload service when an upload is complete.

4. The system of claim 1 , wherein the error table captures, by one or more source systems, a count of a number of errors.

5. The system of claim 1 , wherein the spooler uploads incremental net change data into a master repository via an application layer.

6. The system of claim 5 , wherein the spooler invokes an application programming interface configured for the incremental net change data.

7. The system of claim 1 , wherein the batch data is added to a master repository via a same API and workflow as used by input data to ensure data integrity and security.

8. A method to reduce data loading time from one or more source systems, minimize any effect on the one or more source systems during data loading, and correct any error in the data, comprising:

invoking, by a processor of a master database management computer system, batch data loading of batch data of one or more source systems into an unconstrained area of an input staging area;

automatically selecting, by the processor, one or more staging and master interfaces based on metadata of the one or more source systems;

automatically selecting, by the processor, relational table structures based on semantic mapping metadata;

evaluating, by the processor, the batch data loaded into the input staging area by an error correction workflow, wherein the error correction workflow comprises a structured query language implemented as a stored procedure;

moving, by the processor, any error records into an error table;

correcting, by the processor, any error records in the error table by a spooler within the error correction workflow, wherein the spooler invokes a data upload service which serializes data in XML format and invokes an application programming interface;

loading, by the processor, the batch data from the input staging area and corrected data from the error table into a master repository; and

loading, by the processor, the batch data from the master repository into an output staging area.

9. The method of claim 8 , further comprising:

providing, by the processor, an event node comprising a persist net change node, wherein the error correction workflow waits on the persist net change node until an upload process is complete.

10. The method of claim 8 , further comprising:

issuing, by the processor, a callback by a data upload service when an upload is complete.

11. The method of claim 8 , wherein the error table captures, by one or more source systems, a count of a number of errors.

12. The method of claim 8 , wherein the spooler uploads incremental net change data into a master repository via an application layer.

13. The method of claim 12 , wherein the spooler invokes an application programming interface configured for the incremental net change data.

14. The method of claim 8 , wherein the batch data is added to a master repository via a same API and workflow as used by input data to ensure data integrity and security.

15. A non-transitory computer-readable medium embodied with software to reduce data loading time from one or more source systems, minimize any effect on the one or more source systems during data loading, and correct any error in the data, the software when executed using one or more computers is configured to:

invoke batch data loading of batch data of one or more source systems into an unconstrained area of an input staging area of a master database management computer system;

automatically select one or more staging and master interfaces based on metadata of the one or more source systems;

automatically select relational table structures based on semantic mapping metadata;

evaluate the batch data loaded into the input staging area by an error correction workflow, wherein the error correction workflow comprises a structured query language implemented as a stored procedure;

move any error records into an error table;

correct any error records in the error table by a spooler within the error correction workflow, wherein the spooler invokes a data upload service which serializes data in XML format and invokes an application programming interface;

load the batch data from the input staging area and corrected data from the error table into a master repository; and

load the batch data from the master repository into an output staging area.

16. The non-transitory computer-readable medium of claim 15 , wherein the software when executed is further configured to:

provide an event node comprising a persist net change node, wherein the error correction workflow waits on the persist net change node until an upload process is complete.

17. The non-transitory computer-readable medium of claim 15 , wherein the software when executed is further configured to:

issue a callback by a data upload service when an upload is complete.

18. The non-transitory computer-readable medium of claim 15 , wherein the error table captures, by one or more source systems, a count of a number of errors.

19. The non-transitory computer-readable medium of claim 15 , wherein the spooler uploads incremental net change data into a master repository via an application layer.

20. The non-transitory computer-readable medium of claim 19 , wherein the spooler invokes an application programming interface configured for the incremental net change data.
