Preserving flexibility while using Active Record pattern
Bob Martin believes that Active Record pattern that maps data structures to objects may be a source of confusion. Even though it appears to be an object, it actually is a data structure, vulnerable to the addition of new types. To preserve the flexibility, Bob Martin suggests separating Active Record from the application, so that the latter can be designed and structured solely around objects.

OOP: Thinking beyond verb/noun metaphor to yield a better design
In OOP, objects are traditionally coupled with actions that determine their behavior, implemented as objects’ methods. Reg Braithwaite argues that, in some cases, it may be relevant to dissociate the two. Traditional approach to OOP is also questioned by Buko Obele who advocates for going beyond the verb/noun metaphor that is often used to approach object oriented design.

Confusing unit-of-work with threads
Most server-side applications and many desktop applications contains data that is tied to a particular task that’s being executed. A common solution is to keep that kind of data in thread-local storage; to keep the data in variables bound to the executing thread. Convenient, but a practice based on a faulty assumption.

Defining Design Quality
A good design is elegant and simple - but elegance is in the eye of the beholder. James Shore, in his book 'The Art of Agile Development', disagreed with this abstract concept. In fact, he provided a very concrete definition of design quality: "A good software design minimizes the time required to create, modify, and maintain the software while achieving run-time performance."
