Schema is subset of data model in which just the structure used to store data is there like table in relational whereas data model is larger term in which schema + constraints + relationships n all hota
schema are the actual tables and its relation and including how all database mechanism and features apply to the actual data. on the other hand, a data model is a more generic abstract/conceptual representation of data regardless of how you would implement in database. your database schema should agree to your data model. your data model is like a specification is just an abstract thing.

A data model is a tool which describes the schema and schema is the overall design of the database
schema are the actual tables and its relation and including how all database mechanism and features apply to the actual data. on the other hand, a data model is a more generic abstract/conceptual representation of data regardless of how you would implement in database. your database schema should agree to your data model. your data model is like a specification is just an abstract thing.
