Information features and characteristics of the relational and semantic database

In this paper, we study and study the features of the application of relational data models in most cases is quite sufficient for modelling any data. In practice, the use of formal databases can cause great difficulties, because in the models initially there are no mechanisms for describing the semantics of the domain. In this regard, the emergence of semantic data models that allow us to describe a specific subject area is much closer to an intuitive understanding and, at the same time, in a rather formal way.
