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.
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 relation between computation and the underlying mathematical structures from fields such as logic, set theory, model theory, category theory, etc. It has close links with other areas of computer science such as programming language design, type theory, compilers and interpreters, program verification and model checking.
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).
semantic data integration, and; taxonomies/classification. Given a question, semantic technologies can directly search topics, concepts, associations that span a vast number of sources. Semantic technologies provide an abstraction layer above existing IT technologies that enables bridging and interconnection of data, content, and processes.

A semantic wiki is a wiki that has an underlying model of the knowledge described in its pages. Regular, or syntactic , wikis have structured text and untyped hyperlinks . Semantic wikis, on the other hand, provide the ability to capture or identify information about the data within pages, and the relationships between pages, in ways that can ...
