When Do You Know that Your Data is Healthy? 6 Things to Look

5 Min Read

Every tech website, magazine, and podcast discusses the importance of having healthy data. But if you’re unsure what that means, how do you know if your company’s data is healthy? Through some integral steps and tools, like data observability and data profiling, you can get an accurate picture of your data’s health. Here are some guidelines to help you determine whether your information is healthy.

1. Quality Checks

Quality checks are a must-have for any data-driven project. Performing quality checks on your data helps you identify and remove incorrect, incomplete, or duplicate records from your dataset. Quality checks also help you detect errors in how data is structured or stored, which can cause problems later on when you try to analyze it.

To conduct a quality check, use data profiling tools to compare the structure and content of your data against a set of predefined rules. Data profiling helps you detect outliers, missing values, incorrect or mismatched types, and other errors that can affect the accuracy of your analysis.

2. Data Governance

Having strict guidelines for collecting, cleaning, storing, and using data helps ensure that your data remains accurate and secure. Data governance involves establishing policies, processes, and standards for handling data to ensure its quality and integrity.

Data governance should be a part of any data-driven project. Establishing roles and responsibilities for data management is essential for keeping track of who is responsible for what data and ensuring that everyone follows the same rules when dealing with it.

3. Data Security

Data security is another crucial factor to consider when assessing your data’s health. Ensuring that your information is secure and protected from unauthorized access helps guarantee its accuracy, as well as prevent malicious actors from corrupting or stealing it.

To ensure data security, you must implement strong security measures such as encryption, access control, and multi-factor authentication. You should also regularly back up your data in case of unexpected events.

4. Data Observability

Data observability is a relatively new practice that involves tracking and monitoring all the changes made to an organization’s data in real time. It helps you identify any potential issues with your data before they affect your analysis or reporting.

Data observability also allows you to detect and address problems quickly and accurately, so you can make sure that your data is always up-to-date and accurate.

5. Data Visualization

Using data visualization tools to inspect and analyze your data is a great way to get an overall view of its health. Data visualizations, such as charts and graphs, can help you spot patterns and correlations that would otherwise be difficult to detect. These visualizations also provide an excellent way to communicate complex information quickly, so you can easily understand any trends or problems in your data.

When everyone on your team can visualize and interpret data, it will be easier to make informed decisions. Data charts and graphs can be made using data visualization tools or spreadsheets, such as Excel or Google Sheets. You can also use data analysis tools to create interactive charts and dashboards.

6. Data Cleaning

Data cleaning is an integral part of any data-driven project, as it helps to ensure that your data is accurate and up-to-date. Data cleaning involves removing or correcting invalid or duplicate records, identifying and fixing errors in storing or structured data, and verifying that all necessary information has been captured correctly.

Data cleaning should be done regularly, as data sets tend to accumulate errors over time. This helps ensure that your analysis and reporting are always accurate and consistent. Automating data cleaning processes can also save you time and effort in the long run.

Final Thoughts

Maintaining the health and accuracy of your data is essential for any successful data-driven project. By implementing a few best practices, such as data profiling, governance, security, observability, visualization, and cleaning, you can make sure that your data is always accurate and up-to-date. Doing so will help ensure that your analysis and reporting are reliable and that your team is making informed decisions. ​​​​
