The Expression Builder is a tool used to query data by performing operations and functions.
The Expression Builder provides easy access to the functions, attributes, literals, and operators needed to build expressions appropriate for the context in which you are working.
Use the Expression Builder to:
- Create, validate, and modify business rules and to construct specific data quality standards against which data sources (entities) are validated.
- Create a new attribute (column) in a data source or tab view. See Adding and Editing a Custom Attribute/Column.
- Create a filter to select rows to include in a join.
