Data-detected Data Classes
A data class is defined to identify a data pattern. You can define the data pattern manually or ask the application to learn it automatically from the data and approval actions.
A field or column may be assigned one or more Data-detected and/or Metadata-detected Data Classes. Once that class type is assigned, it is a property of the element and may be searched on, filtered by and further edited (remove the assignment).

E.g., the field in the example above is assigned the data class Gender.
Data classes are based upon a pool, defined repository-wide. This pool includes a unique name for the class and either:
- Enumeration - list of valid values, e.g., Red, Blue, Green.
- Pattern - list of possible patterns, generally discovered by the software, e.g., A{2}9{3}-9{3}-9{3}
- Regular Expression - syntactical rule set.
These are used to infer data classification for objects based upon sampling and profiling the data.
Some actions can apply to all objects of a certain data class. In particular the Hide/Show property.
