Explanation RELATIONAL SCHEMAT: The relational model, a mathematical model invented by Edgar Codd, is a data model for database management based on predicate logic and set theory. 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. In the mathematical model, reasoning about such data is done in two-valued predicate logic, meaning there are two possible evaluations for each proposition: either true or false (and in particular, no third value such as unknown, or not applicable, either of which is often associated with the concept of NULL). Some think that logic (which is inherently two-valued) is an important part of the relational model, where others think that a system that uses a form of three-valued logic can still be considered relational.

- Manual RealSky:
- Help digital photographic sky atlas, which is a subset of the Digitized Sky Survey (DSS) published in 1996 by the Astronomical Society of the Pacific. RealSky is composed of the "RealSky" relational schemat definition.
- Manual Revision Control:
- Help also known as version control or source control, is the management of multiple revisions of the same unit of information and information systems. It is most commonly used in engineering and software relational schemat explain.
- Manual Rematerialization:
- Help is a compiler optimization method which saves time by recomputing a value instead of loading it from memory. It is typically tightly integrated with register allocation, where it is used as an relational schemat what is.
- Manual Rosegarden:
- Help open source digital audio workstation program developed for Linux with ALSA and KDE. It acts as an audio and MIDI sequencer, scorewriter and musical composition and editing tool. It is intended to be relational schemat meaning.
- Manual Register Spilling:
- Help occurs during a program compilation where there are more live variables than the register can hold. When a compiler is generating machine code and there are more live variables than the machine has relational schemat abbreviation.
