Concern (computer science)
In computer science, a concern is a particular set of information that has an effect on the code of a computer program. A concern can be as general as the details of database interaction or as specific as performing a primitive calculation, depending on the level of conversation between developers and the program being discussed. IBM uses the term concern space to describe the sectioning of conceptual information.[1]
Overview
Usually the code can be separated into logical sections, each addressing separate concerns, and so it hides the need for a given section to know particular information addressed by a different section. This leads to a
bugs
in the operation of the program.
Paradigms that specifically address the issue of concern separation:
- Object-oriented programming, describing concerns as objects
- Functional programming, describing concerns as functions
- Aspect-oriented software development, treating concerns and their interaction as constructs of their own standing
