QlikView Data Quality Management

Addressing Data Qualtity Issues can be split into three simple steps:

  1. Define Data Qualtity Rules
  2. Perform data validation and transformation
  3. Report on found issues

Advanced ETL Processor can be used to perform first two, It has 300+ validation/tranformation functions plus it works with 27 datasources. For the third one you can use QlikView.

Everyone who performs data transformation knows the importance of data quality and how much time is required to find what went wrong and correct the problem

In the latest version of Advanced ETL Processor we introduced new object called "Log"

Data Quality LogThe idea is very simple: to redirect log messages into different data flow so this data can used later for reporting.

Plus comparing to standard text log it provides much more information to the user.

It allows to answer the following questions:

What was wrong with the data?
Which actions were taken to correct the data?
Initial value of the field
Value after correction
Source file/table
Record number
Date
Computer name
User name
Customer Name
Person responsible
Date
And much more
