Whois & Analysis for refactoring.guru

In software engineering, a software design pattern is a general reusable solution to a commonly occurring problem within a given context in software design.

It is not a finished design that can be transformed directly into source or machine code.

It is a description or template for how to solve a problem that can be used in many different situations.

Design patterns are formalized best practices that the programmer can use to solve common problems when designing an application or system.

Code refactoring is the process of restructuring existing computer code—changing the factoring—without changing its external behavior.

Refactoring improves nonfunctional attributes of the software.

Advantages include improved code readability and reduced complexity; these can improve source-code maintainability and create a more expressive internal architecture or object model to improve extensibility.

Typically, refactoring applies a series of standardised basic micro-refactorings, each of which is (usually) a tiny change in a computer program's source code that either preserves the behaviour of the software, or at least does not modify its conformance to functional requirements.

Many development environments provide automated support for performing the mechanical aspects of these basic refactorings.

If done extremely well, code refactoring may also resolve hidden, dormant, or undiscovered computer bugs or vulnerabilities in the system by simplifying the underlying logic and eliminating unnecessary levels of complexity.

If done poorly it may fail the requirement that external functionality not be changed, introduce new bugs, or both.

Software design is the process by which an agent creates a specification of a software artifact, intended to accomplish goals, using a set of primitive components and subject to constraints.

Software design may refer to either "all the activity involved in conceptualizing, framing, implementing, commissioning, and ultimately modifying complex systems" or "the activity following requirements specification and before programming, as...

[in] a stylized software engineering process.".

Systems engineering is an interdisciplinary field of engineering and engineering management that focuses on how to design and manage complex systems over their life cycles.

At its core systems engineering utilizes systems thinking principles to organize this body of knowledge.

Issues such as requirements engineering, , logistics, coordination of different teams, testing and evaluation, maintainability and many other disciplines necessary for successful system development, design, implementation, and ultimate decommission become more difficult when dealing with large or complex projects.

Systems engineering deals with work-processes, optimization methods, and risk management tools in such projects.

It overlaps technical and human-centered disciplines such as industrial engineering, mechanical engineering, manufacturing engineering, control engineering, software engineering, electrical engineering, cybernetics, organizational studies, engineering management and project management.

Systems engineering ensures that all likely aspects of a project or system are considered, and integrated into a whole.

In computing, source code is any collection of computer instructions, possibly with comments, written using a human-readable programming language, usually as ordinary text.

The source code of a program is specially designed to facilitate the work of computer programmers, who specify the actions to be performed by a computer mostly by writing source code.

The source code is often transformed by an assembler or compiler into binary machine code understood by the computer.

The machine code might then be stored for execution at a later time.

Alternatively, source code may be interpreted and thus immediately executed.
