 Determine whether the data stored in a model needs to be warehoused. Data should be warehoused if it can contribute to analyzing users' behavior. By default, new models should be warehoused as it's a rare occurrence that meaningful insights cannot be gained from analyzing its data.
 
-Defining a model as a warehouse-model allows us to sync data from our database to our data warehouse before its deleted from our database. See our [data deletion strategy](https://code-for-life.gitbook.io/code-for-life-dev/data/storage#data-deletion-strategy).

-A model's manager should be defined within the model's class as `Manager`. If the model inherits `WarehouseModel`, the manager should inherit `WarehouseModel.Manager`, providing a string of the model's name as the type parameter to inform the manager of the type of model it will be managing. Below the manager's definition, create a class-level attribute on the model called `objects` which has its type set to `Manager` and it's value set to an instance of the `Manager` class.
