Analyzing columns
To understand your data at the lowest level, including its contents, quality, and the accuracy of its metadata, you can analyze columns to examine the properties and characteristics of these columns or fields to find inconsistencies and anomalies.
About this task
Inferences and analysis results help you to make decisions about how you want to manage data. When you complete a column analysis job, you review the results and system inferences and save the metadata. You can examine the summary data for the data fields, change the results that are inferred by the system, and drill down into individual data fields for a detailed view of the data. When you complete your review, you can create reference tables to use information that is gathered during the analysis outside of the column analysis job, add notes during the review, and mark the review as complete.
