Also simply application or app. Computer software designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user. Common examples of applications include word processors, spreadsheets, accounting applications, web browsers, media players, aeronautical flight simulators, console games, and photo editors. This contrasts with system software, which is ...
FizzBuzzEnterpriseEdition offers a humorous example of over-complexity introduced by design patterns. [32] By definition, a pattern must be programmed anew into each application that uses it. Since some authors see this as a step backward from software reuse as provided by components, researchers have worked to turn patterns into components ...
In formal language theory and computer science, Iota and Jot (from Greek iota ι, Hebrew yodh י, the smallest letters in those two alphabets) are languages, extremely minimalist formal systems, designed to be even simpler than other more popular alternatives, such as lambda calculus and SKI combinator calculus.
In astrology (in the context of an astrological chart, birth chart or horoscope), a yod is a specific, planetary alignment that is formed by two planets being sextile to one another (60° apart), with a third planet being exactly 150° to the other two points, or quincunx (also called inconjunct). In essence, the three points add up as 150 ...
NP-hardness of pattern language membership, by reduction from the NP-complete 1-in-3-SAT problem: Given a CNF of m clauses with n variables, a pattern of length 3n+4m+1 with 2n variables and a string of length 4n+5m+1 can be constructed as shown (m=3 and n=4 in the example). Upper-case variables in the pattern correspond to negated variables in ...
The state pattern is a behavioral software design pattern that allows an object to alter its behavior when its internal state changes. This pattern is close to the concept of finite-state machines . The state pattern can be interpreted as a strategy pattern , which is able to switch a strategy through invocations of methods defined in the ...
In computer science, the syntax of a computer language is the rules that define the combinations of symbols that are considered to be correctly structured statements or expressions in that language. This applies both to programming languages , where the document represents source code , and to markup languages , where the document represents data.
To rephrase Zaniolo's definition more simply, the relation is in 3NF if and only if for every non-trivial functional dependency X → Y, X is a superkey or Y \ X consists of prime attributes. Zaniolo's definition gives a clear sense of the difference between 3NF and the more stringent Boyce–Codd normal form (BCNF).
