Outline of software engineering - Wikipedia

From Wikipedia, the free encyclopedia

Overview of and topical guide to software engineering

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.^[1]

The ACM Computing Classification system is a poly-hierarchical ontology that organizes the topics of the field and can be used in semantic web applications and as a de facto standard classification system for the field. The major section "Software and its Engineering" provides an outline and ontology for software engineering.

Software applications[edit]

Software engineers build software (applications, operating systems, system software) that people use.

Applications influence software engineering by pressuring developers to solve problems in new ways. For example, consumer software emphasizes low cost, medical software emphasizes high quality, and Internet commerce software emphasizes rapid development.

Engineering All traditional engineering branches use software extensively. Engineers use spreadsheets, more than they ever used calculators. Engineers use custom software tools to design, analyze, and simulate their own projects, like bridges and power lines. These projects resemble software in many respects, because the work exists as electronic documents and goes through analysis, design, implementation, and testing phases. Software tools for engineers use the tenets of computer science; as well as the tenets of calculus, physics, and chemistry.

A platform combines computer hardware and an operating system. As platforms grow more powerful and less costly, applications and tools grow more widely available.

Computer science topics[edit]

Skilled software engineers know a lot of computer science including what is possible and impossible, and what is easy and hard for software.

Algorithms, well-defined methods for solving specific problems.
Compiler theory
- Yacc/Bison
Data structures, well-defined methods for storing and retrieving data.
- Lists
- Trees
- Hash tables
Computability, some problems cannot be solved at all
- List of unsolved problems in computer science
- Halting problem
Complexity, some problems are solvable in principle, yet unsolvable in practice
