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 t
Data-base management systems (DBMS) provide the user with ways of organising (or modelling) information. This allows the user to work at an abstract, meaningful level without having to deal with the data structures and algorithms necessary to store and Data model Noetica is an information system...

In 2012, Google first promoted a semantic metadata organizational model described as a “knowledge graph” to improve query result relevancy and its overall search experience. Since the development of the semantic web, knowledge graphs are often associated with linked open data projects, focusing on ...

As is typical in all DBMSs, physical operators are related to logical operators, but there exists no one-to-one correspondence between them. In the rest of this section, operators refer to physical operators. 12.2.2 Queues A queue connects its input operator OI to its output oper- ator OO...

an authorization of executing an action must be assigned to a resource (Database) that runs on a system (DBMS) compatible with the action type (Select, Create, Delete). Unique Name Assumption (UNA) Unique Name Assumption (UNA) is a commonly accepted assumption in most model-driven tools. ...
A foreign key occurs when the columns of a primary key of a first table are present in a second table. Many of the commercial database management systems (DBMS's) of today are based on the relational database model. Examples of such systems are Oracle, DB2, Sybase, MS SQL Server, and...
A computer-based system for allowing a user to create a relational database schema. The system allows a user to create a semantic object data model of the database schema. The semantic object data mod
