It is very easy to configure rules for individual properties of the objects stored in Backendless. Available constraints include:
- Not-null – forces saved/updated objects to have a value for the constrained property.
- Unique – property value in the created/updated object must be unique across all other objects in the same table.
- Indexed – indexes the stored values in the column to optimize it for faster searches.
