Chapter 13. Software Architecture: Object-Oriented Versus Functional
One of the arguments for functional programming is better modular design.By analyzing publications advocating this approach, in particular through the example of a framework for financial contracts, we access its strengths and weaknesses, and compare it with object-oriented design. The overall conclusion is that object-oriented design, especially in a modern form supporting high-level routine objects or “agents,” subsumes the functional approach, retaining its benefits while providing higher-level abstractions more supportive of extension and reuse.
Overview
“Beauty,” as a slogan for a software architecture, is not strictly for the beholder to judge. Clear objective criteria exist (Meyer 1997):
- Reliability
Does the architecture help establish the correctness and robustness of the software?
- Extendibility
How easy is it to accommodate changes?
- Reusability
Is the solution general, or better yet, can we turn it into a component to be plugged in directly, off-the-shelf, into a new application?
The success of object technology has largely followed from the marked improvements it brings—if applied properly as a method, not just through the use of an object-oriented programming language—to the reliability, extendibility, and reusability of the resulting programs.
The functional programming approach predates object-oriented thinking, going back to the Lisp language available for almost 50 years. To those fortunate enough ...
