High-quality data is the foundation of every data-driven solution. As companies recognize the value of data and data management, teams are under greater pressure to increase and maintain high data quality. The growing number of data sources and increasing complexity make it challenging for teams to continuously evaluate and improve data quality.

Using data quality tools can help on many fronts. For starters, monitoring and improving data quality is easier and more efficient. Data management gets easier when you have the right level of observability. 

There are many different data quality tools on the market, so how do you find the right one for your use case? 

In this article, we dive into the topic of data quality management tooling and share a list of top data quality tools, from free and open-source solutions to heavy-duty business software packages.

What are Data Quality Tools and How are They Used?

Data quality tools help to streamline and often automate data management activities required to guarantee that data remains fit for analytics, data science, and machine learning use cases. Such tools help teams assess existing data pipelines, identify quality bottlenecks, and automate various remedial tasks.

Profiling data, tracing data lineage, and cleansing data are all examples of processes connected with assuring data quality. Data cleansing, data profiling, measurement, and visualization tools help teams understand the format and values of the acquired data assets and their collection. 

These tools will highlight outliers and mixed formats. In the data analytics pipeline, data profiling acts as a quality control filter. And all of these are key data management functions.

The Importance of Using Data Quality Management Tools

Data quality tools help teams make data more trustworthy and manageable. Inaccurate data leads to bad decisions, missed opportunities, and lower earnings. 

This is why data quality has become a major concern as data sets continue to expand and become more complex. 

Each data quality tool comes with a unique set of features that may fit various use cases. Monitoring capabilities are essential for tracking data quality metrics. When problems are found, they can notify data management teams so that they can investigate them sooner, when they are easier to resolve.

What metrics are we even talking about?

What Data Quality Metrics Should You Track?

Data quality metrics are key for evaluating and assessing the data quality within a company.

First of all, you have the standard data quality dimensions:

Data Quality Dimension Description
Timeliness Data’s readiness within a certain time frame.
Completeness The amount of usable or complete data, representative of a typical data sample.
Accuracy Accurate and reliable data based on the agreed-upon source of truth.
Validity Checks how much data conforms to the acceptable format for any business rules.
Consistency Compares data records from two different datasets.
Uniqueness Tracks the volume of duplicate data in a dataset.

For each of those dimensions such as data accuracy, you can find some relevant metrics:

Data to Errors Ratio

This metric is very important because it gives you an idea of how many errors you can expect in your data set relative to its size. The metric basically counts known errors in a data set and compares this number to the size of that data set. You need this information to know whether your data quality processes work.

Number of Empty Values

Counting how many times an empty field appears in a data set is a good idea as well. Why are empty fields important if they’re empty? Such fields often reflect information that has been entered incorrectly or may be completely missing. Data management tools should pick up on this type of information.

Data Time-to-Value

Another key point: it pays to check how much time it takes your team to extract relevant insights from data. If it takes longer than you thought, at least you’ll have a solid data point to rely on when asking for data quality management tooling.

Data Transformation Error Rate

This metric tracks the frequency with which data transformation activities fail. If you notice this rate going up, you’ll know that it’s time to act now before the issue snowballs into a massive problem.


This metric tracks all the instances when data isn’t available to users when they need it.

Data quality metric you should track What it’s all about
Data to Errors Ratio Counts known errors in a data set and compares them to the size of the data set.
Number of Empty Values Counts how many times an empty field appears in a data set.
Data Time-to-Value Evaluates the amount of time it takes to derive relevant insights from data.
Data Transformation Error Rate Indicates the frequency with which data transformation activities fail.
Timeliness (SLA) Tracks when data is not available to users when they require it.

Benefits of Using Data Quality Tools

Using data quality tools will assist you in better managing and using data. Here are ten key ways data quality technologies can help your organization.

Increases trust in your data

Using a data quality tool increases consumer trust in the data. They’re aware that the data quality tool has eliminated low-quality data, leaving only high-quality data on board – enabling truly data-driven decision-making. 

Enhances decision-making 

Incomplete or inaccurate data can lead to erroneous decisions that can have disastrous consequences for the company’s operations and profitability. The higher the quality of your data, the better your decisions. 

Promotes internal consistency

Poor-quality data might lead to inconsistencies in your organization’s operations, leading individuals and teams to draw various conclusions from different data sets. When everyone across the company uses the same high-quality data, operations, and decision-making become more consistent across departments and regions. 

Improves agility

Competing in a fast-paced environment necessitates agility. Teams won’t be able to act swiftly if the data is wrong or untrustworthy. Access to more and better data enables you to make faster and more agile decisions.

Consider the effort spent attempting to reach former leads who have relocated or changed email addresses. Working with high-quality, up-to-date data can boost productivity dramatically.

Saves time and money

Using data quality technology is less expensive than manual data cleansing. Even more importantly, working with clean data from the start is significantly less expensive than cleaning it later or dealing with the consequences of faulty data. 

Remember the ancient adage: It costs one dollar to check data, ten dollars to clean it after the fact, and one hundred dollars to do nothing and bear the repercussions of faulty data. 

Up to 80% of data practitioners’ time is spent clearing up poor data. Using a data quality solution removes manual effort and saves a tremendous amount of valuable time, allowing team members to focus on other productive tasks.

Enhances regulatory compliance

Every company must follow some type of industry standards. If your data processes are questionable, you may jeopardize your customers’ privacy. Working with higher-quality data helps ensure compliance and avoid harsh financial penalties easier.
