What is the relationship between data quality and refresh intervals?

Data quality and refresh intervals are closely linked. Higher refresh rates can improve data quality by ensuring that the information is up-to-date, but if the data source is unreliable, frequent updates may not enhance quality.

Can you give me examples of how poor data quality affects refresh intervals?

Certainly! If data is inaccurate or outdated, refreshing it frequently can lead to the propagation of errors. For instance, if a sales database is updated every hour but contains incorrect entries, the business decisions based on that data will be flawed.

How can I improve data quality without increasing refresh intervals?

You can improve data quality by implementing data validation rules, using data cleansing techniques, and ensuring that your data sources are reliable. This way, even with less frequent updates, the data remains accurate.

What tools can help with data quality management?

There are several tools available, such as Talend, Informatica, and Microsoft Power BI, which offer features for data quality management, including profiling, cleansing, and monitoring.
