CDQ Data Quality Checker for Data Quality Analysis

The CDQ Data Quality Checker offers global coverage and is not limited to a specific country. Our tool allows your company to quickly and easily evaluate the quality of your business partner data. The data quality services reliably analyse company names, addresses, legal structures, tax ID numbers and company registration IDs, for example. Our data quality check is based on 36 million data sets maintained through open data sources as well as carefully considered quality rules that were crafted together with experienced data management consultants and experts from various international commercial and industrial companies and, thus, best cover the needs of our customers. Furthermore, we also integrate countless reference data from reliable and trustworthy external sources in order to obtain an optimal analysis.

GDPR Check: Reliably Recognise Personal Data

A special feature of our online tool is the recognition of personal data that could be hidden within your business partner data. This identifies unintentional violations of the General Data Protection Regulation (GDPR) so that you can quickly resolve the issues.

Only a Few Clicks to the Data Quality Analysis

The utilisation of our Data Quality Checker is intentionally designed to be simple, in order to make possible an analysis of your business partner data with minimal effort. Here is how it works:

FAQ - Frequently Asked Questions about the Data Quality Check

Our data analysis tool is suited for all companies who want to quickly and simply acquire an overview of the quality level of their global business partners’ data. If you would like to analyse larger data sets or not deliver them in a special format, please contact our data management experts, who will gladly support you.

The use of our data analysis tool is currently free. We reserve the right, however, to offer the Data Quality Check for a fee at a later time.

Each data transmission we receive is protected through up-to-date protocols and encryption mechanisms. The entire CDQ Cloud Engine infrastructure is ran on Amazon Web Service servers in the European Union—in Frankfurt (Germany), for example. All data uploaded in the Data Quality Checker and analysis results are stored in an individual database. If the user chooses to delete the input data and results, then the entire database will be deleted. No data are cached or withheld.

Our app allows one to evaluate an infinite amount of data sets; there is currently no limitation. We reserve the right, however, to limit the service due to excessive use in order to protect our servers. Various files can be evaluated after each other.

You can either send us your data as CSV or Excel files - our online tool offers separate templates for this. These clarify the required data fields with clear terminology. The CDQ Cloud Engine can also handle unstructured data, such as combination entries with streets and house numbers or building information in the same data field—try it out, yourself!

Following the successful analysis of your input data, you will receive the first impression of the data quality in the app in the “Results Overview” window. For example, this could include the number and portion of incorrect entries regarding addresses and legal persons. You will receive a detailed evaluation in the form of a validation report in a CSV or Excel file.

The CDQ Data Quality Tools can currently be used for free and in full for data quality analysis. We reserve the right, however, to offer the tool for a fee at a later time and to limit access due to excess use in order to protect our servers.
