Relational contract theory was originally developed in the United States by the legal scholars Ian Roderick Macneil and Stewart Macaulay. According to Macneil, the theory offered a response to the so-called "The Death of Contract" school’s nihilistic argument that a contract was not a fit subject for study as a whole; each different type of contract (e.g., sales, employment, negotiable ...
The relation between message and reality is of central importance to Gerbner. [133] [131] [132] For this reason, his model includes two dimensions. The horizontal dimension corresponds to the relation between communicator and event. The vertical dimension corresponds to the relation between communicator and message. [139]
Barnlund's model is an influential transactional model of communication. It was first published by Dean Barnlund in 1970. It is formulated as an attempt to overcome the limitations of earlier models of communication. In this regard, it rejects the idea that communication consists in the transmission of ideas from a sender to a receiver.
Databases and other data stores which treat the integrity of data as paramount often include the ability to handle transactions to maintain the integrity of data. A single transaction consists of one or more independent units of work, each reading and/or writing information to a database or other data store.
A relational database (RDB [1]) is a database based on the relational model of data, as proposed by E. F. Codd in 1970. [ 2 ] A database management system used to maintain relational databases is a relational database management system ( RDBMS ).
[5] [6] A relational database definition (database schema, sometimes referred to as a relational schema) can thus be thought of as a collection of named relation schemas. [7] [8] In implementations, the domain of each attribute is effectively a data type [9] and a named relation schema is effectively a relation variable (relvar for short).
Relational dialectics theory deals with how meaning emerges from the interplay of competing discourses. [27] A discourse is a system of meaning that helps us to understand the underlying sense of a particular utterance. Communication between two parties invokes multiple systems of meaning that are in tension with each other.
In contrast to conventional row-orientation, relational databases can also be column-oriented or correlational in the way they store data in any particular structure. In general, substantial performance improvement is gained if different types of database objects that are usually utilized together are laid in storage in proximity, being ...
