A few years ago, a PNI customer asked me to review his PNI integrity checker log files and make recommendations about ignore/fix for each error type. It turns out that there was absolutely no documentation available for understanding the error codes. The only way I could understand the codes was to use global text searches or even
print_users_of()to find the place where the code was raised and then try to deduce what the actual data condition was. Well, that was good for me as a billable consultant, but not so good for the customer.
If they had had a tool like the Data Quality Toolkit, this problem would not have been as acute. What I find particularly nice about the Data Quality Toolkit is the associated QCDB Knowledge Database. This is essentially an on-line wiki that has been keyed to those cryptic error codes. So now, when your integrity checking process encounters an error code, the Data Quality Toolkit gives you a link to the appropriate web page in the Knowledge Database which provides you with a detailed explanation of causes and fixes for that error type. And because this wiki is a living document, if you ever encounter an error code that has not yet been documented, let Realworld ECHO know and they will update the relevant page. The nice thing about that is future users of the service will now automagikally have access to the same analysis. No need to wait for a TSB to be issued with updated documentation. What we have here is a slick use of online tools to improve the data quality of the entire PNI/LNI/Office community.
Good job folks! Keep up the good work.
