To each of the entity types in SDM the formula of first-order language can be assigned. The sets determined by formulas are data relations whose n-tuples consist of property values. SDM is an enhancement of the
we believe that Semantic Web technologies will play a key role in addressing the challenges faced in realization of smart environments such as Smart Oilfields and Smart Cities due to their ability of giving meaning to data for machine-readability, describing data using ontologies, re-using and shar...
Semantics is defined as “the relation of signs to real world entities they represent” [30] i.e., the mapping between the language elements and the real world entities which allows conveying meaning [31]. Languages differ in terms of their formality, both regarding the syntax and the ...
The visualization of the RDF in Table 1. Full size image These standard models allow structured and semi-structured data to be mixed, exposed, and shared across different applications. These technologies formally represent the meaning involved in information. For example, ontology can describe concepts...
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. This approach to data modeling and ...

If it is not, then the intended meaning of a window specification on the subquery result is somewhat ambiguous, so a semantic (type) error is generated, and the author must add an explicit relation-to-stream operator. Example 12 Now we see why the filter query of Example 10 can be ...
