+## Materializations
+
+- Ways in which a model can be stored in the database. There are 4:
+  - View: it's just a view
+  - Table: the model gets stored as a table
+  - Incremental: also a table, but can only create new records, not update
+  - Ephemeral: it's actually NOT materializing. The model can be used by dependents, but it won't be materialized in the DB. It will truly only be a CTE that gets used by other models. Mostly for intermediate states in transformations.
