What Is a Data Model?

PV: I've read a blog post about what really is a data model, as used in the term "relational data model" (RM). It made the following points:

1. The implementation of a data model is a programming language.

2. The RM is not necessary. It is not necessary for developing software solutions, maintaining large shared databases, or any other purpose in the world of software development. Any software solutions that can be developed while employing the RM could be written without it, using other data models.
