Unified Modeling Language

UML logo Unified Modeling Language ( UML ) is a standardized general-purpose modeling language in the field of object-oriented software engineering . The Unified Modeling Language includes a set of graphic notation techniques to create visual models of object-oriented software-intensive systems.

Free On-line Dictionary of Computing

The Free On-line Dictionary of Computing ( FOLDOC ) is an online, searchable, encyclopedic dictionary of computing subjects. [ 1 ] [ 2 ] It was founded in 1985 by Denis Howe and is hosted by Imperial College London . Howe has served as the editor-in-chief since the dictionary's inception, with visitors to the website able to make suggestions for additions or corrections to articles. [ 3 ] The dictionary incorporates the text of other free resources, such as the Jargon File , as well as covering many other computing-related topics. Due to its availability under the GNU Free Documentation License , a copyleft license, it has in turn been incorporated in whole or part into other free content projects, such as Wikipedia .

Visual language

A visual language is a system of communication using visual elements. Speech as a means of communication cannot strictly be separated from the whole of human communicative activity that includes the visual [ 1 ] and the term 'language' in relation to vision is an extension of its use to describe the perception, comprehension and production of visible signs. [ edit ] Overview An image that dramatizes and communicates an idea presupposes the use of a visual language . Just as people can 'verbalize' their thinking, they can 'visualize' it. A diagram , a map , and a painting are all examples of uses of visual language.

KTechlab uses flowcharts to program microcontrollers graphically. In computing , a visual programming language ( VPL ) is any programming language that lets users create programs by manipulating program elements graphically rather than by specifying them textually. A VPL allows programming with visual expressions, spatial arrangements of text and graphic symbols, used either as elements of syntax or secondary notation .

Cognitive dimensions of notations

"Hidden dependency" redirects here. Cognitive dimensions or cognitive dimensions of notations [ 1 ] [ 2 ] are design principles for notations , user interfaces and programming language design , described by researchers Thomas R.G. Green and Marian Petre . The dimensions can be used to evaluate the usability of an existing information artifact , or as heuristics to guide the design of a new one.

In computer programming, homoiconicity is a property of some programming languages , in which the primary representation of programs is also a data structure in a primitive type of the language itself, from the Greek words homo meaning the same and icon meaning representation . This makes metaprogramming easier than in a language without this property. To put that another way, homoiconicity is where a program's source code is written as a basic data structure that the programming language knows how to access.

Homoiconicity

The cognitive walkthrough method is a usability inspection method used to identify usability issues in interactive systems, focusing on how easy it is for new users to accomplish tasks with the system. Cognitive walkthrough is task-specific, whereas heuristic evaluation takes a holistic view to catch problems not caught by this and other usability inspection methods . The method is rooted in the notion that users typically prefer to learn a system by using it to accomplish tasks, rather than, for example, studying a manual. The method is prized for its ability to generate results quickly with low cost, especially when compared to usability testing , as well as the ability to apply the method early in the design phases, before coding has even begun.

Cognitive walkthrough

Software visualization [ 1 ] is the static or animated 2-D or 3-D [ 2 ] visual representation of information about software systems based on their structure, [ 3 ] size, [ 4 ] history, [ 5 ] or behavior. [ 6 ] Typically, the information used for visualization is software metric data from measurement activities or from reverse engineering . Visualization is inherently not a method for software quality assurance but can be used to manually discover anomalies similar to the process of visual data mining . [ 7 ]

Software visualization

In computer programming , dataflow programming is a programming paradigm that models a program as a directed graph of the data flowing between operations, thus implementing dataflow principles and architecture. Dataflow programming languages share some features of functional languages , and were generally developed in order to bring some functional concepts to a language more suitable for numeric processing. [ edit ] Properties of dataflow programming languages Dataflow programming focuses on how things connect , unlike imperative programming , which focuses on how things happen .
