Database normalization. Database normalization is the process of structuring a relational database in accordance with a series of so-called normal forms in order to reduce data redundancy and improve data integrity. It was first proposed by British computer scientist Edgar F. Codd as part of his relational model .
Clipping (morphology) In linguistics, clipping, also called truncation or shortening, [1] is word formation by removing some segments of an existing word to create a synonym. [2] Clipping differs from abbreviation, which is based on a shortening of the written, rather than the spoken, form of an existing word or phrase.
Symplectic manifold. In differential geometry, a subject of mathematics, a symplectic manifold is a smooth manifold, , equipped with a closed nondegenerate differential 2-form , called the symplectic form. The study of symplectic manifolds is called symplectic geometry or symplectic topology. Symplectic manifolds arise naturally in abstract ...
Third normal form ( 3NF) is a database schema design approach for relational databases which uses normalizing principles to reduce the duplication of data, avoid data anomalies, ensure referential integrity, and simplify data management. It was defined in 1971 by Edgar F. Codd, an English computer scientist who invented the relational model for ...
Heterozygous example. In a heterozygous genotype, the two different alleles interact with each other. This determines how their traits are expressed. Commonly, this interaction is based on ...
The simplest example of a vector space is the trivial one: {0}, which contains only the zero vector (see the third axiom in the Vector space article). Both vector addition and scalar multiplication are trivial. A basis for this vector space is the empty set, so that {0} is the 0- dimensional vector space over F.
Microsoft account logo. A Microsoft account or MSA (previously known as Microsoft Passport,.NET Passport, and Windows Live ID) is a single sign-on personal user account for Microsoft customers to log in to consumer Microsoft services (like Outlook.com), devices running on one of Microsoft's current operating systems (e.g. Microsoft Windows computers and tablets, Xbox consoles), and Microsoft ...
An example of a captive web portal used to log onto a restricted network. A captive portal is a web page accessed with a web browser that is displayed to newly connected users of a Wi-Fi or wired network before they are granted broader access to network resources.
