U+27D7 Full Outer Join

U+27D7 was added in Unicode version 3.2 in 2002. It belongs to the block U+27C0 para U+27EF Miscellaneous Mathematical Symbols-A in the U+0000 para U+FFFF Basic Multilingual Plane.

This character is a Puntuación matemática and is commonly used, that is, in no specific script.

The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+27D7 forms with similar adjacent characters prevents a line break inside it.

El Wikipedia tiene la siguiente información acerca de este punto de código:

In database theory, relational algebra is a theory that uses algebraic structures for modeling data, and defining queries on it with a well founded semantics. The theory was introduced by Edgar F. Codd.

The main application of relational algebra is to provide a theoretical foundation for relational databases, particularly query languages for such databases, chief among which is SQL. Relational databases store tabular data represented as relations. Queries over relational databases often likewise return tabular data represented as relations.

The main purpose of relational algebra is to define operators that transform one or more input relations to an output relation. Given that these operators accept relations as input and produce relations as output, they can be combined and used to express complex queries that transform multiple input relations (whose data are stored in the database) into a single output relation (the query results).

Unary operators accept a single relation as input. Examples include operators to filter certain attributes (columns) or tuples (rows) from an input relation. Binary operators accept two relations as input and combine them into a single output relation. For example, taking all tuples found in either relation (union), removing tuples from the first relation found in the second relation (difference), extending the tuples of the first relation with tuples in the second relation matching certain conditions, and so forth.

Other more advanced operators can also be included, where the inclusion or exclusion of certain operators gives rise to a family of algebras.
