The Suitability of Using Objects for Modeling at the Systems Level

摘要

Functional analysis has been the traditional approach to modeling systems. Now that object-oriented analysis has essentially displaced structured analysis for software development, it is reasonable to ask whether objects should go on to replace functiosn for modeling at all levels of system definition. Issues related to modeling notations, methods, and resulting analytical flexibilities are discussed. While the object oriented notations and methods have grown significantly in the past few years, they may not yet be ready to replace functional analysis at the system level.
