About Data Policies
Use a data policy when you want to apply row-level security to one or more tables in the connection. Data policies apply to both live and extract connections.
A data policy has three main components:
- The tables it applies to, called policy tables. These are the tables that are filtered.
- The mapped columns that define the relationships between tables (for example, between entitlement and fact tables) and between table columns and policy columns. A policy column is the column used to filter data.
- The policy condition, which is an expression that is evaluated for every row at query time. When TRUE, the row is shown in the query.
