Application software is any computer program that is intended for end-user use – not operating, administering or programming the computer. An application (app, ...
Custom software (also known as bespoke software or tailor-made software) is software that is developed specifically for some specific organization or other user. As such, it can be contrasted with the use of out-of-the-box software packages developed for the mass market , such as commercial off-the-shelf software, or existing free software .
An API opens a software system to interactions from the outside. It allows two software systems to communicate across a boundary — an interface — using mutually agreed-upon signals. [3] In other words, an API connects software entities together. Unlike a user interface, an API is typically not visible to users. It is an "under the hood ...
The Carnegie Mellon Software Engineering Institute defines a software product line as "a set of software-intensive systems that share a common, managed set of features satisfying the specific needs of a particular market segment or mission and that are developed from a common set of core assets in a prescribed way."
Software metering tools monitor the utilization of software applications across a network. They can also provide real-time enforcement of compliance for applications licensed based on usage. Application control tools restrict what and by whom particular software can be run on a computer as a means of avoiding security and other risks. [6]
Software engineering is a field within computer science and a branch of engineering focused on designing, developing, testing, and maintaining of software applications. It involves applying engineering principles and computer programming expertise to develop software systems that meet user needs.
A software development kit (SDK) is a collection of software development tools in one installable package. They facilitate the creation of applications by having a compiler, debugger and sometimes a software framework. They are normally specific to a hardware platform and operating system combination.
The design should "minimize the intellectual distance" between the software and the problem as it exists in the real world. That is, the structure of the software design should, whenever possible, mimic the structure of the problem domain. The design should exhibit uniformity and integration. A design is uniform if it appears fully coherent.
