 1. dbt will run a "preflight" check to ensure that the model's query will return a set of columns with names and data types matching the ones you have defined. This check is agnostic to the order of columns specified in your model (SQL) or YAML spec.
 2. dbt will include the column names, data types, and constraints in the DDL statements it submits to the data platform, which will be enforced while building or updating the model's table.
 
+## Platform constraint support
+
+Select the adapter-specific tab for more information on [constraint](/reference/resource-properties/constraints) support across platforms. Constraints fall into three categories based on support and platform enforcement:
+
+- **Supported and enforced** — The model won't build if it violates the constraint.
+- **Supported and not enforced** — The platform supports specifying the type of constraint, but a model can still build even if building the model violates the constraint. This constraint exists for metadata purposes only. This is common for modern cloud data warehouses and less common for legacy databases.
+- **Not supported and not enforced** — You can't specify the type of constraint for the platform.

+Currently, `not_null` and `check` constraints are supported and enforced only after a model builds. Because of this platform limitation, dbt considers these constraints `supported` but `not enforced`, which means they're not part of the "model contract" since these constraints can't be enforced at build time. This table will change as the features evolve.
