7 Best Data Quality Management Tools

0

Data quality management tools can automate many of the processes needed to ensure that data remains fit for purpose in analytics, data science, and machine learning use cases. Organizations need to find the most suitable tool to assess existing data pipelines, identify quality bottlenecks, and automate various remediation steps.

Processes associated with data quality assurance include data profiling, data lineage tracking, and data cleansing. Overall, it might be a good idea to identify a tool or set of tools that aligns with the company’s existing data pipeline workflows. In the short term, it is sometimes useful to identify specific gaps or challenges in the data quality process.

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

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

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

Similarities and differences of tools

Each data quality tool has its own set of features and workflows. Most tools include data profiling, cleaning, and normalization features.

You can learn a lot about the quality of your data by using the right profiling tools.

Data profiling, measurement, and visualization features help teams understand the format and values ​​of the collected data set. These tools will flag outliers and mixed formats. Data profiling serves as a quality correction filter in the data analysis 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 normalization capabilities help identify inconsistent data formats, values, names, and outliers in current data sets. Then they can apply a normalization, such as an address validator, pattern check, formatter, or synonym database, to the data pipeline to always return a normalized value. This is useful when the same data is entered in different ways.

Data cleansing features can help fix structural issues, remove outliers, fill in missing data fields, and ensure required fields are filled in correctly. Data cleansing can be expensive, considering the extra hours and tools required. Look for tools that can fill data cleansing gaps in existing workflows, Sage said.

Analytical capabilities help break data down into its component parts. This can help track the cause of data quality issues and flag downstream datasets when issues arise in a data pipeline.

Monitoring capabilities track data quality metrics. When issues are detected, they can alert data management teams to investigate sooner, when they’re easier to fix.

Here are seven of the best data quality management tools:
