The text says that a semantic data model is sometimes called conceptual data model.
Does that mean, that it is just a synonym and the two articles could be merged? Or is there any difference in meaning?

Terms are used very fuzzy and different among authors but you can separate semantic data[base] models = conceptual data[base] models and logical data models. A "schema" in both cases is a model expressed in a specific modeling language. So a "conceptual schema" is a semantic data model expressed in ERM, UML, ORM or similar language. -- JakobVoss ( talk) 05:40, 16 July 2010 (UTC)
The qualifier "semantic" suggests that an 'ordinary' data model is *not* semantic. This is patently false: any data model is a representation of object classes/types and the stereotypical relationship types between them. That is semantic. I suspect that the term is invented by someone who really has little understanding of data modelling generally, nor what the term "semantics" means (excuse the pun) — Preceding unsigned comment added by 76.169.22.32 ( talk) 17:19, 16 May 2014 (UTC)
This article is very incomplete. People such as Jean-Raymond Abrial introduced the first semantic data models in the early 1970s to allow models to get closer to domain descriptions in natural language. That problem was widely discussed at the time. Their work should at least be mentioned. Rp ( talk) 10:42, 30 March 2022 (UTC)
