A semantic data model in software engineering has various meanings: It is a conceptual data model in which semantic information is included. This means that the model describes the meaning of its instances. Such a semantic data model is an abstraction that defines how the stored symbols (the instance data) relate to the real world. [1]
Overview of a data-modeling context: Data model is based on Data, Data relationship, Data semantic and Data constraint. A data model provides the details of information to be stored, and is of primary use when the final product is the generation of computer software code for an application or the preparation of a functional specification to aid a computer software make-or-buy decision.

A semantic asset is a specific type of standard which involves: highly reusable metadata (e.g. xml schemata, generic data models) and/or reference data (e.g. code lists, taxonomies, dictionaries, vocabularies) Organisations use semantic assets to share information and knowledge (within themselves and with others).
That is unless the semantic data model is implemented in the database on purpose, a choice which may slightly impact performance but generally vastly improves productivity. Semantic data models. [8] Therefore, the need to define data from a conceptual view has led to the development of semantic data modeling techniques. That is, techniques to ...
The ISO/IEC 11179 model is a result of two principles of semantic theory, combined with basic principles of data modelling. The first principle from semantic theory is the thesaurus type relation between wider and more narrow (or specific) concepts, e.g. the wide concept "income" has a relation to the more narrow concept "net income".
A semantic grid is an approach to grid computing in which information, computing resources and services are described using the semantic data model.In this model, the data and metadata are expressed through facts (small sentences), becoming directly understandable for humans.
