When is Object Oriented not the correct solution?
architecture, language-agnostic, oop
Solution
Some problems are best expressed using other paradigms such as Functional Programming. Also, declarative paradigms allow more robust formal reasoning about the correctness of the code. See Erlang for a good example of a language with certain advantages that can't really be matched by OO languages due to the fundamental nature of the paradigm.
Examples of problem domains where other language paradigms have a better fit are database queries (SQL), expert systems (Prolog, CLIPS etc.) or Statistical computing (R).
Problem
I've encountered lately some opinions saying that Object Oriented design/programming should not always be used. Do you know some use-cases that will not benefit from and should not use Object Oriented design? For example: there are some problems (concerns) that will benefit from AOP.
