Semantic data model vs. conceptual data model

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?

The problem here is that there is no real article about conceptual data model, just about conceptual schema, which if I am not mistaken is more about database modeling. -- Marcel Douwe Dekker (talk) 21:26, 20 July 2009 (UTC)[reply]
You are right. I also know the term "conceptual schema" from the database context (ANSI-SPARC Architecture). Then probably, it is not correct to use the terms "conceptual schema" and "conceptual data model" synonymously like it is done here: conceptual schema. On the other hand these terms are used very inconsistently in literature (some authors claim that "conceptual schema" is not the same as "conceptual data model" / others use these terms interchangeably). --80.136.42.27 (talk) 18:15, 21 July 2009 (UTC)[reply]
