Software engineering is a field within computer science 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.
The following outline is provided as an overview of and topical guide to software engineering: . Software engineering – application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software; that is the application of engineering to software.
Software development involves many skills and job specializations including programming, testing, documentation, graphic design, user support, marketing, and fundraising. Software development involves many tools including: compiler, integrated development environment (IDE), version control, computer-aided software engineering, and word processor.
The integrated circuit is an essential invention to produce modern software systems. [2] The first use of the word software is credited to mathematician John Wilder Tukey in 1958. [3] The first programmable computers, which appeared at the end of the 1940s, [4] were programmed in machine language.
The use of rapid-prototyping evolved to entire lightweight methodologies, such as Extreme Programming (XP), which attempted to simplify many areas of software engineering, including requirements gathering and reliability testing for the growing, vast number of small software systems. Very large software systems still used heavily documented ...
Computer-aided software engineering (CASE) is a domain of software tools used to design and implement applications. CASE tools are similar to and are partly inspired by computer-aided design (CAD) tools used for designing hardware products. CASE tools are intended to help develop high-quality, defect-free, and maintainable software. [1]
Systems engineering techniques are used in complex projects: printed-circuit-board design, robotics, bridge building, software integration, and spacecraft design. Systems engineering uses a host of tools that include modeling and simulation, requirements analysis, and scheduling to manage complexity.
In software and systems engineering, the phrase use case is a polyseme with two senses: A usage scenario for a piece of software; often used in the plural to suggest situations where a piece of software may be useful. A potential scenario in which a system receives an external request (such as user input) and responds to it.
