What does a data profiling tool help with?

• A. Creating new data models
• B. Exploring data content and validating it against metadata
• C. Establishing the relationships of data in a canonical model
• D. Maintaining data lineage records

Answer: (B)

A data profiling tool is primarily designed to explore the content of data and validate it against its associated metadata. This process involves examining the data to assess its quality, structure, patterns, and characteristics, which can include checking for completeness, uniqueness, consistency, and validity. By validating data against metadata, which provides context about the data's structure, meaning, and constraints, organizations can gain insights into the data's fitness for use and identify potential issues that may need to be addressed. This capability is crucial for data quality management, as it helps organizations understand their data assets better and ensure that the data they rely on for decision-making is accurate and trustworthy. Additionally, data profiling can inform decisions when creating new data models or establishing relationships in data structures, but its primary focus remains on assessing and validating data content against defined characteristics and rules within the metadata framework.
