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.

The relational interpretation makes no fundamental distinction between the human experimenter, the cat, or the apparatus, or between animate and inanimate systems ; all are quantum systems governed by the same rules of wavefunction evolution, and all may be considered " observers.

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 ).

# There is a relational character to the divine which allows God to experience both the joy and suffering of humanity.

The flexibility of relational databases allows programmers to write queries that were not anticipated by the database designers.

Together with the ability to string multiple header / data blocks together, this allows FITS files to represent entire relational databases.

* 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, ...),

WinFS includes a relational database for storage of information, and allows any type of information to be stored in it, provided there is a well defined schema for the type.

Each partner in a relationship is supported in a way that allows an exploration of the internal relational dynamics in each person, and a growing understanding of how these dynamics are played out in the relationship.

By combining a fourth generation language and relational database, OpenEdge ABL allows the use of the Rapid Application Development ( RAD ) model for developing software.

Windows Installer allows applications to run directly from a network share, without the need for a local copy ( run from source ); it can repair broken installations by restoring damaged or deleted files, registry entries and application shortcuts ; it supports per-user installation of applications ; it can resolve component identifiers into paths, allowing applications to avoid hard-coded file paths ; and it natively supports patches (. msp files made out of patch creation properties ) and other customizations of packages through manipulations ( transforms or. mst files ) of a package's relational database.

This allows an object model to map well to a relational database's data model.

Jet allows the manipulation of a relational database and is part of a Relational Database Management System ( RDBMS ).

A dynamic form of relational tools that allows ad-hoc columns may relax schema bound-ness, but such tools are currently rare.

* Access rules — In relational databases, attributes are accessed and altered through predefined relational operators, while OO allows each class to create its own state alteration interface and practices.

OO tends to argue that relational standards limit expressiveness, while relational proponents suggest the rule adherence allows more abstract math-like reasoning, integrity, and design consistency.

Conceptually, a Dataset object can be seen as a small in-memory relational database in its own right that allows for manipulation of data in any direction.

It allows data organised by the relational entity – attribute model to be serialised into XML, binary, or SQLite stores.

PL / Perl, as an imperative programming language, allows more control than the relational algebra of SQL.

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.

Those non-relational databases are significantly different from the classic relational databases.

This same couple may emphasize different aspects of intercourse on different occasions, being playful during one episode of intercourse ( recreational ), experiencing deep emotional connection on another occasion ( relational ), and later, after discontinuing contraception, seeking to achieve pregnancy ( reproductive, or more likely reproductive and relational ).

Object databases are different from relational databases and belongs together to the broader database management system.

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.

After the relational model was defined, there were many attempts to compare and contrast the different models, and this led to the emergence of more rigorous descriptions of the earlier models ; though the procedural nature of the data manipulation interfaces for hierarchical and network databases limited the scope for formalization.

The essential idea behind relational quantum mechanics, following the precedent of special relativity, is that different observers may give different accounts of the same series of events: for example, to one observer at a given point in time, a system may be in a single, " collapsed " eigenstate, while to another observer at the same time, it may be in a superposition of two or more states.

The field of sexology provides different psychological evaluation devices in order to examine the various aspects of the discomfort, problem or dysfunction, regardless of whether they are individual or relational ones.

A good ETL tool must be able to communicate with the many different relational databases and read the various file formats used throughout an organization.

The IMS Database component stores data using a hierarchical model, which is quite different from IBM's later released relational database, DB2.

Since effective usage of the object-oriented paradigm requires a different thought process than used with conventional procedural or database languages, standard methodologies such as structure charts, data flow diagrams, and traditional data design models ( hierarchical, relational, and network ) are not sufficient.

Rather, ANT is a way of thoroughly exploring the relational ties within a network ( which can be a multitude of different things ).

After 1990, increased attention to cultural dimensions and to comparative and relational history moved German historiography to different topics, with much less attention paid to the Sonderweg.

PowerDNS features a large number of different backends ranging from simple BIND style zonefiles to relational databases and load balancing / failover algorithms.

Differences in structure occur when two data models provide different primitives such as object oriented ( OO ) models that support specialization and inheritance and relational models that do not.

Individuals may experience relational ambiguity from being in different stages of the coming out process or having an HIV serodiscordant relationship.

Current high end relational database management systems provide for different criteria to split the database.

Not all application bindings for relational database systems adhere to that standard, and some ( such as CLI or JDBC ) use a different interface.

Although it can be used in many contexts and among different age groups, relational aggression among adolescents, in particular, has received a lot of attention with the help of popular media including movies like ‘’ Mean Girls ’’ and books like ‘’ Odd Girl Out ’’ by R. Simmons ( 2003 ) and ‘’ Queen Bees and Wannabes ’’ by R. Wiseman ( 2003 ).

It should be noted that both normalized – and dimensional models can be represented in entity-relationship diagrams as both contain joined relational tables.

DBMSs can be categorized according to the database model ( s ) that they support, such as relational or XML, the type ( s ) of computer they support, such as a server cluster or a mobile phone, the query language ( s ) that access the database, such as SQL or XQuery, performance trade-offs, such as maximum scale or maximum speed or others.

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.

It has also been suggested that space and distance themselves are relational, and that an electron can appear to be in " two places at once " – for example, at both slits – because its spatial relations to particular points on the screen remain identical from both slit locations.

Positive and negative discrete emotions can be strategically displayed to influence task and relational outcomes and may play out differently across cultural boundaries.

Access to data can be faster because joins are often not needed ( as in a tabular implementation of a relational database ).

Due to the relational nature of many built-in predicates, they can typically be used in several directions.

The European view of public relations notes that besides a relational form of interactivity there is also a reflective paradigm that is concerned with publics and the public sphere ; not only with relational, which can in principle be private, but also with public consequences of organizational behavior.

A relational database is a collection of data items organized as a set of formally described tables from which data can be accessed easily.

In The Third Manifesto ( first published in 1995 ) Date and Darwen show how the relational model can accommodate certain desired object-oriented features.

As a result, relational databases can be used by multiple applications in ways the original designers did not foresee, which is especially important for databases that might be used for a long time ( perhaps several decades ).

It tells us that in every instance of a certain relational schema the tuples can be identified by their values for certain attributes.

While it is true that a workbook that contains three sheets is indeed a file containing multiple tables that can interact with each other, it lacks the relational structure of a database.

Typically, input documents are XML files, but anything from which the processor can build an XQuery and XPath Data Model can be used, for example relational database tables, or geographical information systems.

When considering indirect forms of non-violent aggression, such as relational aggression and social rejection, some scientists argue that females can be quite aggressive although female aggression is rarely expressed physically.

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

All of these points can be addressed in a proper relational system, although the SQL standard and its implementations impose arbitrary restrictions and additional complexity

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.

Metadata can include information such as author and time of creation, and this can be stored in a relational database.
