What Is Data Profiling?: Making Sure Your Data is Definitive
The data profiling process is your secret weapon in your fight for good data. It is the process of evaluating the content and quality of data. The goal of data profiling is to determine how accurate, complete, and valid the dataset is. A data wrangler’s understanding of an overall dataset is informed by the statistical analysis of values for logic and consistency, otherwise known as data profiling. Data profiling tools evaluate quality by exploring frequency distributions of different values both within and across tables or columns. With good data profiling, the implementation cycle for a project is made shorter and discovering business intelligence embedded deep within the data is possible. Learn about the types and benefits of data profiling and how to improve your data profiling abilities.
