In computer science, a relational operator is a programming language construct or operator that tests or defines some kind of relation between two entities. These include numerical equality (e.
Relational art
TENDENCY IN FINE ART
Relational Aesthetics; Relational Esthetics; L'esthétique relationnelle; Relational Art; Esthétique relationnelle; Relation Aesthetics; Relation Art
Relational art or relational aesthetics is a mode or tendency in fine art practice originally observed and highlighted by French art critic Nicolas Bourriaud. Bourriaud defined the approach as "a set of artistic practices which take as their theoretical and practical point of departure the whole of human relations and their social context, rather than an independent and private space.
Statistical relational learning
SUBDISCIPLINE OF ARTIFICIAL INTELLIGENCE
Probabilistic relational model; Relational probabilistic model
Statistical relational learning (SRL) is a subdiscipline of artificial intelligence and machine learning that is concerned with domain models that exhibit both uncertainty (which can be dealt with using statistical methods) and complex, relational structure.

DATABASE MANAGEMENT SYSTEM
ORDBMS; Object-relational database management system; Object–relational; Object-relational model; Object-relational DBMS; Object-relational dbms; Object relational database; Object-relational database; Object-relational; Object–relational model
An object–relational database (ORD), or object–relational database management system (ORDBMS), is a database management system (DBMS) similar to a relational database, but with an object-oriented database model: objects, classes and inheritance are directly supported in database schemas and in the query language. In addition, just as with pure relational systems, it supports extension of the data model with custom data types and methods.

Transfer operator
PUSHFORWARD ON THE SPACE OF MEASURABLE FUNCTIONS
Ruelle operator; Perron-Frobenius operator; Perron-Frobenius Operator; Frobenius-Perron operator; Bernoulli operator; Ruelle-Frobenius-Perron operator; Frobenius–Perron operator; Perron–Frobenius operator
In mathematics, the transfer operator encodes information about an iterated map and is frequently used to study the behavior of dynamical systems, statistical mechanics, quantum chaos and fractals. In all usual cases, the largest eigenvalue is 1, and the corresponding eigenvector is the invariant measure of the system.

VECTOR'S DIFFERENTIAL OPERATOR
Nabla constant; Atled; Nabla operator; Del operator; Vector differential; Vector differential operator; Gradient operator; Divergence operator
Del, or nabla, is an operator used in mathematics (particularly in vector calculus) as a vector differential operator, usually represented by the nabla symbol ∇. When applied to a function defined on a one-dimensional domain, it denotes the standard derivative of the function as defined in calculus.

Unbounded operator
LINEAR OPERATOR DEFINED ON A DENSE LINEAR SUBSPACE
Closed operator; Closeable operator; Closable operator; Closed unbounded operator; Closure of an operator; Unbounded linear operator
In mathematics, more specifically functional analysis and operator theory, the notion of unbounded operator provides an abstract framework for dealing with differential operators, unbounded observables in quantum mechanics, and other cases.
Object–relational mapping
PROGRAMMING TECHNIQUE
Object-relationship modelling; Object-Relationship Modelling; O/R mapping; O/RM; Post-relational database; Object relational mapper; Object-SQL mapping; Object-Relational Mapping; Object Relational Mapping; Object/relational mapping; Object-relational mapper; O-RM; Object-Relational mapping; O/R mapper; Object relational mapping; Object-relational mapping
Object–relational mapping (ORM, O/RM, and O/R mapping tool) in computer science is a programming technique for converting data between type systems using object-oriented programming languages. This creates, in effect, a "virtual object database" that can be used from within the programming language.
