DataScan class

Represents a user-visible job which provides the insights for the related data source.

For example:

• Data Quality: generates queries based on the rules and runs against the data to get data quality check results.
• Data Profile: analyzes the data in table(s) and generates insights about the structure, content and relationships (such as null percent, cardinality, min/max/mean, etc).
