In computer science, separation of concerns (sometimes abbreviated as SoC) is a design principle for separating a computer program into distinct sections. Each section addresses a separate concern , a set of information that affects the code of a computer program.
Because of confusion around the word "reason", he later clarified his meaning in a blog post titled "The Single Responsibility Principle", in which he mentioned Separation of Concerns and stated that "Another wording for the Single Responsibility Principle is: Gather together the things that change for the same reasons. Separate those things ...
Cross-cutting concerns can be directly responsible for tangling, or system inter-dependencies, within a program. Because procedural and functional language constructs consist entirely of procedure calling, there is no semantic through which two goals (the capability to be implemented and the related cross-cutting concern) can be addressed ...
This allows a programmer to describe where and when additional code should be executed in addition to already-defined behavior. Pointcut permits the addition of aspects to existing software, as well as the design of software with a clear separation of concerns, wherein the programmer weaves (merges) different aspects into a complete application.
The principles of service-oriented design stress the separation of concerns in the software. Applying service-orientation results in units of software partitioned into discrete, autonomous, and network-accessible units, each designed to solve an individual concern. These units qualify as services. [1] [2]
This emphasizes the separation of concerns among components. [1] [2] To find the right level of component granularity, software architects have to continuously iterate their component designs with developers. Architects need to take into account user requirements, responsibilities and architectural characteristics. [3]
Separation of content and presentation (or separation of content and style) is the separation of concerns design principle as applied to the authoring and presentation of content. Under this principle, visual and design aspects (presentation and style) are separated from the core material and structure (content) of a document.
