Code reuse is the practice of using existing source code to develop software instead of writing new code. Software reuse is a broader term that implies using any existing software asset to develop software instead of developing it again. [1] [2]: 7 An asset that is relatively easy to reuse and offers significant value is considered highly ...
Software reusability, the use of knowledge or artifacts from existing systems to build new ones, is a key software engineering technology important both to engineers and managers. Reuse research has been very active. Many organizations have reported reuse successes, yet there are still important research issues in systematic reuse. There is a ...
In software engineering, many reuse metrics and models are metrics used to measure code reuse and reusability. A metric is a quantitative indicator of an attribute of a thing. A model specifies relationships among metrics. Reuse models and metrics can be categorized into six types: reuse cost-benefits models; maturity assessment; amount of ...
Program comprehension (also program understanding or [source] code comprehension) is a domain of computer science concerned with the ways software engineers maintain existing source code. The cognitive and other processes involved are identified and studied. [1] The results are used to develop tools and training. [2]
The ability to reuse can be viewed as the ability to build larger things from smaller parts, and to identify commonality among the parts. Reusability is often a required characteristic of platform software. Reusability brings several aspects to software development that do not need to be considered when reusability is not required.
Don't repeat yourself" (DRY), also known as "duplication is evil", is a principle of software development aimed at reducing repetition of information which is likely to change, replacing it with abstractions that are less likely to change, or using data normalization which avoids redundancy in the first place.
Composition over inheritance (or composite reuse principle) in object-oriented programming (OOP) is the principle that classes should favor polymorphic behavior and code reuse by their composition (by containing instances of other classes that implement the desired functionality) over inheritance from a base or parent class. [2]
A piece of software is typically rewritten when one or more of the following apply: its source code is not available or is only available under an incompatible license; its code cannot be adapted to a new target platform; its existing code has become too difficult to handle and extend; the task of debugging it seems too complicated
