NodeGraph: Your solution to data quality

Scott Duthie - Partner

Today, more than ever, data quality management is a serious concern for most organizations. From poor data entry to an absence of proper governance, the lack of resources and allocations to data quality is hampering many business’s success. According to a 2019 Global Data Management Research survey conducted by Experian, “95% of organizations see impacts from poor data quality” and over “84% of CEO’s worry about their organizations’ data quality” (2016 Global CEO Outlook, KPMG). So what are organizations doing to improve and maintain the quality of their data? For many businesses, NodeGraph is the solution to their data integrity issues.

NodeGraph is a data quality platform for all Qlik solutions that allows you to explore, visualize and trace where your data comes from. Business users are often faced with questions like: “Where did this field come from?”, “What applications are using this particular file?”, and “If I change this database table, what applications will be affected?”.

Well, NodeGraph can help answer those questions. NodeGraph scans both QlikView and Qlik Sense files to produce a graphical representation of your applications and the underlying data with an easy to navigate interface. Select a node and trace the lines of your data lineage through transformed QVDs all the way back to the source database. Search, filter and drill in any direction from applications, QVDs, source tables, fields, charts or SQL queries. Your data’s lineage is truly at your fingertips.

So, without further ado, let’s jump into a few of the exciting and value added features NodeGraph provides.

Data Catalog

The Data Catalog, with a Google-like appearance and functionality, allows users to search into their data and see all related fields, expressions, tables, files, and applications. Select a result and dig deeper by applying filters to examine the ancestry and other important metadata, add comments and ratings for inter-platform communication, and so much more. The Data Catalog provides complete transparency and, with a seamless interface, allows for further exploration into your data

Dependency Explorer

Visualize how your data travels throughout your Qlik Solution from the data source to the end-user application or reporting. One has the option to add layers to see how specific users have interacted with the data along the lineage or enabling application content to trace how master items, sheets, objects, and variables are derived from the source data. Grade the different nodes with a heat map based on users, children, file size, fields/records, and/or last modified time. With a simple right-click on a node, the tool will auto-generate documentation (PDF or MS Word) on the entire lineage with all data sources, transformations, and expressions used in the selected application.

Field Explorer

The Field Explorer provides a detailed documentation that will allow you to examine the script of an individual field. See exactly what transformations have been applied to the field from initial input to production.


Govern, review and assess your Qlik solutions with the help of the Reports module by making sure your data is structured according to your guidelines.
