7 top data quality management tools

Data quality management tools can automate many of the processes required to ensure data remains fit for purpose across analytics, data science and machine learning use cases. Organizations must find the tool that is best to assess existing data pipelines, identify quality bottlenecks and automate various remediation steps.

Processes associated with ensuring data quality include profiling data, tracking data lineage and cleaning data. Overall, it might make sense to identify a tool or set of tools that aligns with the enterprise’s existing data pipeline workflows. In the short run, it is sometimes helpful to identify specific gaps or challenges in the data quality process.

“It’s best to focus first on which tools and systems need to be replaced,” said Jeff Brown, team lead for BI projects at Syntax, a managed service provider.

This starts by working with the teams to determine what will have the most significant effect on improving data-driven culture.

Top considerations include overall cost, ability to audit, ease of setting up policies and standards, amount of training required to use the tool, whether the tool can scale to keep up with increasing and evolving data sources, and ease of use, said Terri Sage, CTO of 1010data, a provider of analytical intelligence to the financial, retail and consumer markets.

Tools similarities and differences

Each data quality tool has its own set of capabilities and workflows. Most tools include features for profiling, cleansing and standardizing data.

Data profiling, measurement and visualization capabilities help teams understand the format and values of the collected data set. These tools will point out outliers and mixed formats. Data profiling serves as a quality fix filter in the data analytics pipeline.

“You can learn a lot about the quality of your data by using the right profiling tools,” said Christophe Antoine, vice president of global solutions engineering at Talend, an open source data integration platform.

Data standardization capabilities help identify inconsistent data formats, values, names and outliers in the current data sets. Then, they can apply a standardization, such as an address validator, pattern check, formatter or database of synonyms, to the data pipeline to always return a standardized value. This is helpful when the same data is input in different ways.

Data cleansing capabilities can help fix structural issues, remove outliers, fill in missing data fields and ensure mandatory fields are correctly filled. Data cleansing can be expensive, given the extra hours and tooling involved. Look for tools that can fill in any data cleansing gaps in existing workflows, Sage said.

Parsing capabilities help to decompose data into its component parts. This can help track the cause of data quality issues and flag downstream data sets when problems arise in a data pipeline.

Monitoring capabilities track data quality metrics. When problems are detected, they can alert data management teams to investigate sooner, when they are easier to address.

Here are seven of the top data quality management tools:

Ataccama One Data Quality Suite

Ataccama was founded in 2007 to commercialize the data preparation tools developed in house by Adastra, a data analytics and AI platform.
