Question

I have to create an Activity diagram that describes data cleansing.

Here is my diagram
1. start
2. system A transfers data
3. system B retrieves data
4.is data inconsistent or consistent with application?
5. if its consistent: diagram ends
6. if its inconsistent: we have to identify the errors in the data
7. fix errors
8. give data to application or program to run
9. application can or can not process data?
10. Can not process: you would have to go through data again
11. fix errors
12.and give the data back to the application to running once again. This will go on till the erro

Answer 1

13. If It can process the data: the diagram ends

Can someone tell me if this is the right process of data cleansing? thank you

Answer 2

One problem I see is that the program does nothing with the result. Also, data cleansing seems like a database term. That would usually be inside one program. If it were error correction, that would seem like something between multiple programs. Or at least that is how it seems to me.
