The database schema is the structure of a database described in a formal language supported typically by a relational database management system (RDBMS). The term " schema " refers to the organization of data as a blueprint of how the database is constructed (divided into database tables in the case of relational databases ).
The export schema helps in managing flow of control of data. Federated Schema is an integration of multiple export schemas. It includes information on data distribution that is generated when integrating export schemas. [3] External schema is extracted from a federated schema, and is defined for the users/applications of a particular federation ...
The school was originally called the University of Lebanon, changing its name effective September 4, 1964 to reflect the location of its campus. The university's first classes were held in space leased in downtown Dallas in the fall of 1965. [1] Robert J. Morris in front of University of Plano 1970
The logical schema was the way data were represented to conform to the constraints of a particular approach to database management. At that time the choices were hierarchical and network. Describing the logical schema, however, still did not describe how physically data would be stored on disk drives. That is the domain of the physical schema.
[4] [5] Supporting schema evolution is a difficult problem involving complex mapping among schema versions and the tool support has been so far very limited. The recent theoretical advances on mapping composition [ 6 ] and mapping invertibility, [ 7 ] which represent the core problems underlying the schema evolution remains almost inaccessible ...

Schema-agnostic queries can be defined as query approaches over structured databases which allow users satisfying complex information needs without the understanding of the representation (schema) of the database. Similarly, Tran et al. [4] defines it as "search approaches, which do not require users to know the schema underlying the data ...
