According to the relational interpretation of quantum mechanics, first proposed by Carlo Rovelli, observations such as those in the double-slit experiment result specifically from the interaction between the observer ( measuring device ) and the object being observed ( physically interacted with ), not any absolute property possessed by the object.

To fully appreciate the relational model of data it is essential to understand the intended interpretation of a relation.

" But the relational interpretation allows that different observers can give different accounts of the same series of events, depending on the information they have about the system.

In 1994 Rovelli introduced the relational interpretation of quantum mechanics, based on the idea that the quantum state of a system must always to be interpreted as relative to another physical system ( like the " velocity of an object " is always relative to another object, in classical mechanics ).

An object database stores complex data and relationships between data directly, without mapping to relational rows and columns, and this makes them suitable for applications dealing with very complex data.

On the other hand, Base One makes the case for extreme scalability without departing from mainstream relational database technology.

Norman's 1988 definition makes the concept of affordance relational rather than subjective or intrinsic.

Wikka's backend is based on a MySQL relational database, which makes it fast, reliable and more scalable than wiki engines based on flat text storage.

A statement in SQL ends a transaction within a relational database management system ( RDBMS ) and makes all changes visible to other users.

This database terminology makes assurances about the data state which are BASE ( Basically Available, Soft state, Eventual consistency ), this stands in contrast to other, more traditional relational databases whose data has ACID ( Atomicity, Consistency, Isolation, Durability ).

This makes it difficult to know whether the stated non-developer perspective of relational is inherent to relational, or merely a product of current practice and tool implementation assumptions.

Further, there is no reason that relational normalization concepts cannot be applied to CODASYL databases however, in the final tally, CODASYL was very complex and required significant training and effort to produce useful applications.

The relational model requires there to be no significance to any ordering of the attributes of a relation.

While this kind of thinking is inherent in object-oriented design, relational databases have no explicit support for inheritance.

In object-relational databases, the approach is essentially that of relational databases: the data resides in the database and is manipulated collectively with queries in a query language ; at the other extreme are OODBMSes in which the database is essentially a persistent object store for software written in an object-oriented programming language, with a programming API for storing and retrieving objects, and little or no specific support for querying.

Ferenczi's rupture with Rank cut short radical innovations in practice, and left no one in the inner circle who would champion relational, pre-Oedipal or " here-and-now " psychotherapy.

In practice the restrictions have no adverse effect on the applicability of his relational algebra for database purposes.

In any case, whether or not adhering to traditional relational concepts, there appears to be no limit in sight to database scalability.

There is no clear agreement across the industry as to what constitutes " Hybrid OLAP ", except that a database will divide data between relational and specialized storage.

Unlike relational databases, which had SQL as the standard query language, and widespread APIs such as ODBC, JDBC and OLEDB, there was no such unification in the OLAP world for a long time.

In many cases the primary key is an auto generated integer which has no meaning for the business entity being represented, but solely exists for the purpose of the relational database-commonly referred to as a surrogate key.

Even if such repackaged non-relational products eventually gave way to SQL DBMSs, no popular " relational " DBMSs are actually relational, be it by Codd ’ s twelve rules or by the more formal definitions in his papers, in his books or in succeeding works in the academia or by its coworkers and successors, Christopher J.

Unlike disk-optimized relational databases such as the Oracle database, DB2, Informix, and SQL Server, TimesTen's data is located entirely in memory ; no disk I / O is required for query operations.

George H. Smith uses an attribute-based approach in an attempt to prove that there is no concept for the term " God ": he argues that there are no meaningful attributes, only negatively defined or relational attributes, making the term meaningless.

The relational model – where data is described in terms of tables and columns – had just been recognized as a data organization theory but no software existed to support that approach.

A superkey is defined in the relational model of database organization as a set of attributes of a relation variable for which it holds that in all relations assigned to that variable, there are no two distinct tuples ( rows ) that have the same values for the attributes in this set.

The deputies had no set term of office, although in practice it was about four month long, from their election at a regional sejmik, to their report on the next sejmik dedicated to hearing and discussing the previous sejm's proceedings ( those sejmiks were known as relational or debriefing ).

Entity integrity is one of the key concepts of relational databases, and ensures that no two records can be identical, that is, have fields containing identical values.

Date and others, that a truly relational DBMS would pose no such problem < ref >.</ ref >, as domains and classes are essentially one and the same thing.

The dominant model in use today is the ad hoc one embedded in SQL, despite the objections of purists who believe this model is a corruption of the relational model since it violates several fundamental principles for the sake of practicality and performance.

The fundamental assumption of the relational model is that all data is represented as mathematical n-ary relations, an n-ary relation being a subset of the Cartesian product of n domains.

* reasoning mechanisms are based on graph notions, basically the classical notion of graph homomorphism ; this allows, in particular, to link basic reasoning problems to other fundamental problems in computer science ( problems on conjunctive queries in relational databases, constraint satisfaction problem, ...),

Design decisions in System R, as well as some fundamental algorithm choices ( such as the dynamic programming algorithm used in query optimization ), influenced many later relational systems.

Rosen's theory differed from other relational views in defining fundamental relations in nature ( as opposed to merely epistemic relations we might discuss ) as information transfers between natural systems and their organization ( as expressed in models ).

* Has an XML document as its fundamental unit of ( logical ) storage, just as a relational database has a row in a table as its fundamental unit of ( logical ) storage.

A naïve mapping between classes and relational schemata is a fundamental design mistake ; and that individual tuples within a database table ( relation ) ought to be viewed as establishing relationships between entities ; not as representations for complex entities themselves.

The distinction between tuples in the relational model and those in set theory is only superficial ; the above example can be interpreted as a 2-tuple if an arbitrary total order is imposed on the attributes ( e. g. ) and then the elements are distinguished by this ordering rather than by the attributes themselves.

However, more recent research has shown that, while men and women do not differ between independence and interdependence generally, they do differ in the distinction between relational and collective interdependence.

Because the relational model emphasizes search rather than navigation, it does not make relationships between different entities explicit in the form of pointers, but represents them rather using primary keys and foreign keys.

In a relational database clustering the two respective relations " Items " and " Orders " results in saving the expensive execution of a Join operation between the two relations whenever such a join is needed in a query ( the join result is already ready in storage by the clustering, available to be utilized ).

Alternatively, and especially in connection with the relational model of database management, the relation between attributes drawn from a specified set of domains can be seen as being primary.

Researchers who employ relational ethics value and respect the connection between themselves and the people they study, and " between researchers and the communities in which they live and work " ( Ellis, 2007, p. 4 ).

To a certain extent, general relativity can be seen to be a relational theory, in which the only physically relevant information is the relationship between different events in space-time.

The relational dimension focuses on the character of the connection between individuals.

Consequently, if quantum mechanics is to be a complete theory, relational quantum mechanics argues that the notion of " state " describes not the observed system itself, but the relationship, or correlation, between the system and its observer ( s ).

An independent relational approach to quantum mechanics was developed in analogy with David Bohm's elucidation of special relativity, in which a detection event is regarded as establishing a relationship between the quantized field and the detector.

Females between the ages of 10 and 14, around puberty age, show a more extreme rate of relational aggression compared to boys.

Compared to traditional techniques of exchange between an object-oriented language and a relational database, ORM often reduces the amount of code that needs to be written.

An object-relational database can be said to provide a middle ground between relational databases and object-oriented databases ( OODBMS ).

The basic goal for the Object-relational database is to bridge the gap between relational databases and the object-oriented modeling techniques used in programming languages such as Java, C ++, Visual Basic. NET or C #.

Traveling frequently between France and America, Rank lectured at universities such as Harvard, Yale, Stanford, and University of Pennsylvania on relational, experiential and “ here-and-now ” psychotherapy, art, the creative will, and “ neurosis as a failure in creativity ” ( Rank, 1996 ).

The theme of the manifestos is how to avoid the ' object-relational impedance mismatch ' between object-oriented programming languages and relational database management systems.

It is usually written in the form of a pair of expressions denoting the values in question, with a relational sign between them indicating the specific inequality relation.

Deception is a major relational transgression that often leads to feelings of betrayal and distrust between relational partners.

A significant amount of deception occurs between romantic and relational partners.

Deception detection between relational partners is extremely difficult, unless a partner tells a blatant or obvious lie or contradicts something the other partner knows to be true.
