Frequently asked questions about data quality
What is data quality?
Data quality is a measure of the condition of data based on characteristics such as its integrity, validity, uniqueness, accuracy, timeliness, consistency and reliability. Data that is of high quality is well-suited to serve its specific purpose.
From a business perspective, data quality can have a major impact on the ability of a company to gather business insights, make strategic decisions and improve operational efficiency and other business outcomes. Common issues that can compromise data quality include poorly defined data, incomplete data, duplicate data, incorrect data and data that is not securely stored.
Data quality is measured by organizations using various methods, like the data quality assessment framework, so they can identify and fix data issues before these turn into bigger business problems. It is common for organizations to perform data asset inventories to establish a baseline of data quality and then to measure and improve based on those baseline scores.
What are data quality tools?
Data quality tools are used to monitor and analyze business data, determining if the quality of the data makes it useful enough for business decision-making while also defining how data quality can be improved. This can include gathering data from multiple data sources, such as databases, emails, social media, IoT and data logs, and effectively scrubbing, cleaning, analyzing and managing the data to make it ready for use.
Combing through datasets to find and fix duplicate entries, fix formatting issues and correct errors can use up valuable time and resources. Although data quality can be improved through manual processes, using data quality tools increases the effectiveness, efficiency and reliability of the process.
Why are data quality tools important?
Companies are increasingly taking a data-driven approach to their decision-making. This includes decisions regarding product development, marketing, sales and other functions of the business.
And there is certainly no lack of data available for these decisions. However, the quality of data remains an issue. According to Gartner, poor data quality costs companies $12.9 million on average every year.
One of the advantages of using data for decision-making is that businesses can derive valuable, quantitative insights to achieve positive outcomes such as reduced costs, increased revenue, improved employee productivity, increased customer satisfaction, more effective marketing campaigns and an overall bigger competitive advantage.
The effectiveness of business decisions is directly related to the quality of data, which is why data quality tools are so important. They help extract greater value from data and allow businesses to work with a larger volume of data, using less time and resources to comb through data and maintain its quality. Data quality tools offer various features that can help sort data, identify issues and fix them for optimal business outcomes.
Key features of data quality tools
Data profiling
Data profiling allows users to analyze and explore data to understand how it is structured and how it can be used for maximum benefit. This feature can include tools for analyzing data patterns, data dependencies and the ability to define data quality rules.
Connectivity
Data quality solutions that offer connectivity features let users gather data from different sources of relevant enterprise data, including internal and external data. Many data quality solutions offer custom connectors and prebuilt connectors to help simplify the connectivity process.
Data parsing
Data parsing allows the conversion of data from one format to another. A data quality tool uses data parsing for data validation and data cleansing against predefined standards. Another important benefit of data parsing is that it allows for error and anomaly detection. In addition, advanced data parsing features offer automation tools, which are particularly useful for large volumes of data.
Data matching
Data matching algorithms help identify and eliminate duplicate data. It also allows users to merge similar records from different sources to minimize data inconsistencies. Some applications offer advanced data matching features that facilitate data record linkage, which establishes a connection between related data, even if the data is not an exact duplicate.
Monitoring and notifications
Monitor data throughout the data lifecycle and notify administrators and management of any issues that need to be addressed. This may include the ability to define data quality KPIs and have access to real-time data quality insights. Some advanced applications allow for customizable alerts.
Data cleaning and standardization
Data cleaning and standardization help identify incorrect or duplicate data and modify it according to predefined requirements. With this feature, users can ensure data exists in consistent formats across datasets. In addition, data cleaning helps enrich data by filling in missing values from internal or external data sources.
Benefits of data quality software
With accurate and reliable data, organizations can make data-driven business decisions. On the other hand, with poor data quality, organizations can draw false conclusions, leading to lost opportunities and a waste of time and resources.
Some of the top benefits of data quality software include:
- Organizations get better accuracy of analytics applications, which are often vital to business decision-making, and with high-quality data, they can expand their use of BI dashboards and tools.
- A software application helps make the process more efficient and minimizes the chances of errors as well as the cost of identifying and fixing data quality issues.
- With data quality software, data management teams can automate repetitive or recurring tasks so they can focus on more productive tasks.
- Data quality software makes it easier for organizations to meet their compliance, regulatory and reporting requirements.
- Data quality tools provide increased access to reliable data, which can be used to improve customer experience.
- With high data quality, organizations are in a good position to adapt to new technologies and the evolving or dynamic nature of business.
