Data model and database schema

I need to test my understanding of the difference between the data model and database schema. According to my understanding, the data model is a description of how the data will be stored and the relationships between the data. While the schema is very similar to a database model and according to the book “Database Management systems ” by Raghu and Johannes ” A description of data in terms of a data model is called schema” and it’s a template of how the data will be stored. Is that right?
