Relational data mining there are relational classification rules (relational classification), relational regression tree, and relational association rules.
Relational calculus Relational calculus consists of two calculi, the tuple relational calculus and the domain relational calculus, that are part of the relational model for databases and provide a declarative way to specify database queries. This in contrast to the relational algebra, which is also part of the relational model but provides a more procedural way for specifying queries.
Relational operator An expression created using a relational operator forms what is termed a "relational expression" or a "condition". Relational operators can be seen as special cases of logical predicates.
Relational dialectics There are four main concepts that form the backdrop of relational dialectics, as well as four major assumptions. Relational Dialectics assumes that "(1.) relationships are not linear, (2.) relational life is characterized by change, (3.) contradiction is the fundamental fact of relational life, and (4.) communication is central to organizing and negotiating relational contradictions".
Relational model SQL, initially pushed as the standard language for relational databases, deviates from the relational model in several places. The current ISO SQL standard doesn't mention the relational model or use relational terms or concepts. However, it is possible to create a database conforming to the relational model using SQL if one does not use certain SQL features.
Relational database Queries made against the relational database, and the derived relvars in the database are expressed in a relational calculus or a relational algebra. In his original relational algebra, Codd introduced eight relational operators in two groups of four operators each. The first four operators were based on the traditional mathematical set operations:
Database model Some post-relational products extend relational systems with non-relational features. Others arrived in much the same place by adding relational features to pre-relational systems. Paradoxically, this allows products that are historically pre-relational, such as PICK and MUMPS, to make a plausible claim to be post-relational.
Relational theory Someone who has constructed a relational theory or promotes relational theorising is called a relationist.
Relational psychoanalysis Psychoanalyst and historian Henry Zvi Lothane has also criticized some of the central ideas of relational psychoanalysis, from both historical and psychoanalytic perspectives. Historically, Lothane believes relational theorists overstate the non-relational aspects of Freud as ignore its relational aspects. Lothane maintains that, though Freud's theory of disorder is "monadic," i.e. focused more or less exclusively on the individual, Freud's psychoanalytic method and theory of clinical practice is consistently dyadic or relational. From a theoretical perspective, Lothane has criticized the term "relational" in favor of Harry Stack Sullivan's term "interpersonal". Lothane developed his concepts of "reciprocal free association" as well as "dramatology" as ways of understanding the interpersonal or relational dimension of psychoanalysis.
Relational transgression Relational transgressions occur when people violate implicit or explicit relational rules. These transgressions include a wide variety of behaviors.
Relational database The various software systems used to maintain relational databases are known as a relational database management system (RDBMS).
Relational sociology Italian sociologist Pierpaolo Donati is one of the founders of relational sociology in Europe and published "Relational Sociology: A New Paradigm for the Social Sciences" in 2011. Also in 2011, British sociologist Nick Crossley published "Towards Relational Sociology".
Relational contract The Unpacking Relational Contracting white paper also describes a five-step process for developing a relational contract:
Enhanced entity–relationship model Textbook discussing implementation in relational and object-relational databases:
Relational art Writer and director Ben Lewis has suggested that relational art is the new "ism", in analogue with "ism"s of earlier periods such as impressionism, expressionism and cubism. Lewis finds many similarities between relational art and earlier "ism"s at their beginnings: relational art is often not considered art at all because it redefines the concept of art, many artists considered "relational" deny that they are such, and relational art had a "founding" exhibition.
Relational sociology In 2010, the University of California-Davis hosted a conference on relational work, organized by Fred Block which resulted in a special issue on "Relational Work in Market Economics" in Politics & Society. Relational work is a sociological concept created by a relational. economic sociologist, Viviana Zelizer. This conference included the work of Frederick Wherry, Jennifer Haylett, Sarah Quinn, Josh Whitford and Nina Bandelj.
Relational database management system A second school of thought argues that if a database does not implement all of Codd's rules (or the current understanding on the relational model, as expressed by Christopher J Date, Hugh Darwen and others), it is not relational. This view, shared by many theorists and other strict adherents to Codd's principles, would disqualify most DBMSs as not relational. For clarification, they often refer to some RDBMSs as "truly-relational database management systems" (TRDBMS), naming others "pseudo-relational database management systems" (PRDBMS).
Melvin Earl Maron Quite remarkably, Maron also pioneered relational databases, proposing a system called the Relational Data File in 1967, on which Ted Codd based his Relational model of data.
Relational algebra The main application of relational algebra is providing a theoretical foundation for relational databases, particularly query languages for such databases, chief among which is SQL.
