When loading data and creating your data model, you can examine the data available from your data source, and collect statistics or summaries from your data model. The purpose of these statistics may be to do the following:

• Find out whether the data tends to a particular standard of quality
• Add metadata using tags or descriptions 
• Discover the frequency and analyze if the data should be cleansed or transformed

You can profile your data model using the Data manager or the Data model viewer.
