An SDM, also known as a semantic database model, can be understood as a conceptual model. It is a data model defined on a higher level that captures the databases’ semantic description, structure, and form.
What is semantic model?
What Does Semantic Data Model Mean? The semantic data model is a method of structuring data in order to represent it in a specific logical way. It is a conceptual data model that includes semantic information that adds a basic meaning to the data and the relationships that lie between them.
What are semantics in database?
Semantic data is data that has been structured to add meaning to the data. This is done by creating data relationships between the data entities to give truth to the data and the needed importance for data consumption. Semantic data helps with the maintenance of the data consistency relationship between the data.
Why do we need semantic model?
At its most basic, semantic modeling is used to depict the relationships that exist among specific values of data, such as the example below that models the same topic as the data modeling diagram above, but now focused on the values of the data and the relationship they have.

What is the benefit of semantic?
Semantic AI applications can use a company’s knowledge graph to classify data, both text and databases, and map out its interconnections. Once this is done, algorithms require less data to produce relevant results because they can analyze not only the data itself but also its context.
What are the 4 different types of data models?
What are the types of data modeling? The three primary data model types are relational, dimensional, and entity-relationship (E-R). There are also several others that are not in general use, including hierarchical, network, object-oriented, and multi-value.
