A conceptual model completely independent

百花草

Abstract
Several authors have pointed out that current conceptual models have two main shortcomings.First, they are clearly oriented to
a specific development paradigm (structured, objects, etc.). Second, once the conceptual models have been obtained, it is really
difficult to switch to another development paradigm, because the model orientation to a specific development approach.This fact
induces problems during development, since practitioners are encouraged to think in terms of a solution before the problem at hand
is well understood, thus anticipating perhaps bad design decisions.
An appropriate analysis task requires models that are independent of any implementation issues.In concrete, models should
support developers to understand the problem and its constraints before any solution is identified.This paper proposes such an
alternative approach to conceptual modelling, called ‘‘problem-oriented analysis method’’.
