A relational database is a database consisting of relation variables (which are also called *relvars*, *R-tables* or just *tables*). The definition, manipulation and integrity rules of relational databases are based on relational operations equivalent to or similar to the Relational Algebra and Calculus. Relational database principles are the basis of a substantial part of data management theory and practice.

Targeted Questions
This tag is appropriate for questions concerning the relational model, relational database-design and relational database implementation.
The SQL language is commonly used to specify relational database-designs and to define and solve relational database problems. However, DBMSs based on SQL are by definition not rdbmss and therefore not all SQL questions are relevant to the relational database tag. Questions specific to sql or its implementations should be tagged accordingly.
