I am trying to figure out the difference between information and conceptual models. For me, both terms seem to mean be the same, but I cannot find a reference where this is established. They are never used together; maybe because they are from different domains?
My question is: What is the difference between information model and conceptual model?
A domain consists of objects, relationships, and concepts we commit ourselves to a specific way of viewing domains. [...] In the field of information systems, this commitment to viewing domains in a particular way is called the conceptual model. [Antoni Olivé. 2007. Conceptual Modeling of Information Systems. Springer-Verlag, Berlin, Heidelberg.]
An information model is a representation of concepts, relationships, constraints, rules, and operations to specify data semantics for a chosen domain of discourse. The advantage of using an information model is that it can provide shareable, stable, and organized structure of information requirements for the domain context. [Y. Tina Lee, Charles R.
