User Interface Management Systems
A User Interface Management System (UIMS) is a mechanism for cleanly separating process or business logic from Graphical user interface (GUI) code in a computer program. UIMS are designed to support N-tier architectures by strictly defining and enforcing the boundary between the business logic and the GUI. A fairly rigid Software architecture is nearly always implied by the UIMS, and most often only one paradigm of separation is supported in a single UIMS. A UIMS may also have libraries and systems such as graphical tools for the creation of user interface resources or data stores. Generally, you cannot easily use multiple UIMS systems at the same time, so choosing the correct model for your UIMS is a critical design decision in any project. The choice of system is dependent upon the system(s) you wish to create user interfaces for, and the general style of your application. For example, if you want to create a web based front end, or just a standalone application or both that wou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Business Logic
In computer software, business logic or domain logic is the part of the program that encodes the real-world business rules that determine how data can be created, stored, and changed. It is contrasted with the remainder of the software that might be concerned with lower-level details of managing a database or displaying the user interface, system infrastructure, or generally connecting various parts of the program. Details and example Business logic: * Prescribes how business objects interact with one another * Enforces the routes and the methods by which business objects are accessed and updated Business rules: * Model real-life business objects (such as accounts, loans, itineraries, and inventories) Business logic comprises: * Workflows that are the ordered tasks of passing documents or data from one participant (a person or a software system) to another. Business logic should be distinguished from business rules. Business logic is the portion of an enterprise system which det ...

Model–view–controller
Model–view–controller (MVC) is a software architectural pattern commonly used for developing user interfaces that divide the related program logic into three interconnected elements. This is done to separate internal representations of information from the ways information is presented to and accepted from the user. Traditionally used for desktop graphical user interfaces (GUIs), this pattern became popular for designing web applications. Popular programming languages have MVC frameworks that facilitate the implementation of the pattern. __TOC__ History One of the seminal insights in the early development of graphical user interfaces, MVC became one of the first approaches to describe and implement software constructs in terms of their responsibilities. Trygve Reenskaug created MVC while working on Smalltalk-79 as a visiting scientist at the Xerox Palo Alto Research Center (PARC) in the late 1970s.

CLIM
The Common Lisp Interface Manager (CLIM) is a Common Lisp-based programming interface for creating user interfaces, i.e., graphical user interfaces (GUIs). It provides an application programming interface (API) to user interface facilities for the programming language Lisp. It is a fully object-oriented programming user interface management system, using the Common Lisp Object System (CLOS) and is based on the mechanism of stream input and output. There are also facilities for output device independence. It is descended from the GUI system Dynamic Windows of Symbolics' Lisp machines between 1988 and 1993. The main development was CLIM 2.0, released in 1993. It is free and open source software released under a GNU Library General Public License (LGPL). CLIM has been designed to be portable across different Common Lisp implementations and different windowing systems. It uses a reflective architecture for its window system interface. CLIM supports, like Dynamic Windows, so-called Pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seeheim Model
Seeheim is a settlement in the ǁKaras Region of southern Namibia. The only notable structures in Seeheim today are the hotel and the railway station; only a handful of people live there. Seeheim belongs to the Keetmanshoop Rural electoral constituency. History Seeheim was founded in 1896 as a base for the German Schutztruppe. Early in the 20th century its sole purpose was that of a junction station where the lines from Keetmanshoop diverted to Lüderitz and Karasburg. The line Keetmanshoop-Lüderitz was built from 1905 to 1908, the line Keetmanshoop-Karasburg in 1909. The First World War was the reason to build these railway links through inhospitable land. Soon however, transport demand peaked due to the diamond rush that developed after a railway worker picked up a diamond near Grasplatz station, 24 kilometers east of Lüderitz. People travelling from the inland to Lüderitz had to stay overnight at Seeheim junction. This was the reason for the erection of two hotels, one of ...

Model–view–presenter
Model–view–presenter (MVP) is a derivation of the model–view–controller (MVC) architectural pattern, and is used mostly for building user interfaces. In MVP, the ''presenter'' assumes the functionality of the "middle-man". In MVP, all presentation logic is pushed to the presenter. History The model-view-presenter software pattern originated in the early 1990s at Taligent, a joint venture of Apple Inc., Apple, IBM, and Hewlett-Packard. MVP is the underlying programming model for application development in Taligent's C++-based CommonPoint environment. The pattern was later migrated by Taligent to Java (programming language), Java and popularized in a paper by Taligent CTO Mike Potel. After Taligent's discontinuation in 1998, Andy Bower and Blair McGlashan of Dolphin Smalltalk adapted the MVP pattern to form the basis for their Smalltalk user interface framework. In 2006, Microsoft began incorporating MVP into its documentation and examples for user interface programming ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squeak
Squeak is an object-oriented, class-based, and reflective programming language. It was derived from Smalltalk-80 by a group that included some of Smalltalk-80's original developers, initially at Apple Computer, then at Walt Disney Imagineering, where it was intended for use in internal Disney projects. The group would later go on to be supported by HP labs, SAP, and most recently, Y Combinator. Squeak runs on a virtual machine (VM), allowing for a high degree of portability. The Squeak system includes code for generating a new version of the VM on which it runs, along with a VM simulator written in Squeak. Developers Dan Ingalls, an important contributor to the Squeak project, wrote the paper upon which Squeak is built, and constructed the architecture for five generations of the Smalltalk language. Alan Kay is an important contributor to the Squeak project, and Squeak incorporates many elements of his proposed Dynabook concept. User interface frameworks Squeak includes four ...

Graphical User Interface
The GUI ( "UI" by itself is still usually pronounced . or ), graphical user interface, is a form of user interface that allows users to interact with electronic devices through graphical icons and audio indicator such as primary notation, instead of text-based UIs, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of CLIs ( command-line interfaces), which require commands to be typed on a computer keyboard. The actions in a GUI are usually performed through direct manipulation of the graphical elements. Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices, smartphones and smaller household, office and industrial controls. The term ''GUI'' tends not to be applied to other lower-display resolution types of interfaces, such as video games (where HUD (''head-up display'') is preferred), or not including flat screens like volumetric displays because ...
