-It represents a shift in the way you typically approach a problem using procedural/structured programming thinking. With procedural/structured programming thinking, a developer will typically think in terms of, "What needs to //happen//?" It tends to focus on creating a set of functions or subroutines to do the things that need to get done. The modularity in procedural programming derives primarily from the "verbs" in the system.+It represents a shift in the way you typically approach a problem when using procedural/structured programming. With procedural/structured programming thinking, a developer typically thinks in terms of, "What needs to //happen//?" It tends to focus on creating a set of functions or subroutines to do the things that need to get done. Thus, the modularity in procedural programming derives primarily from the "verbs" in the system.
  
-In object-oriented thinking, you start with, "What are the components (objects) that make up the problem?" Once you identify those, you then ask, "How do they behave?" and then, "How do the components interact?" The modularity in object-oriented thinking derives primarily from the "nouns" in the system.+In object-oriented thinking, you start with, "What are the components (i.e., objects) that make up the problem?" Once you identify those, you then ask, "How do they behave?" and then, "How do the components interact?" So, the modularity in object-oriented thinking derives primarily from the "nouns" in the system.
  
-While it is possible to analyze and design systems (i.e., applications) using this approach and implement the design in any language, the implementation is made //much// easier and more robust when the language has the necessary support for defining and using objects. Such a language is an **object-oriented language**.+You can //analyze// and //design// your problem using this //object-oriented// perspective and then implement the design in any language. However, the implementation is made //much// easier and more robust when the language has the necessary support for defining and using objects. Such a language is an **object-oriented language**.
  
 So, OOAD facilitates a higher level of modular thinking. And, especially with an object-oriented language, it allows for very effective project management of large applications. So, OOAD facilitates a higher level of modular thinking.
