Relation Algebrais a procedural query language for RDBMS (RelationalDatabase Management System). An Algebra based on the set of operators (like Arithmetic operator, union, intersection relational operator, etc.) and operand. Edgar F. Codd created it for a relational database. Relational Algebra pro...

Algorithms translating SQL statements into equivalent combinations of a core set of relational algebra's operators are well-known, in the context of query processing in DBMS design [73]. In practice, this idea should be refined, as SQL allows non-relational constructs like rows ordering and ...
Bibliographical Notes Codd's original paper can be found in ([Codd (1970)]). In that paper, Codd also in- troduced the original definition of relational algebra. This work led to the prestigious ACM Turing Award to Codd in 1981 ([Codd (1982)]). After E. F. Codd introduced the ...

In this Chapter, we consider relational databases as a data source for the generation of Linked Data, given that they constitute one of the most popular data storage media, containing huge data volumes that feed the vast majority of information systems worldwide. In this context, we review the...
