Compare the traditional model and stable pattern of accessibility by using the following adequacies:

• Descriptive Adequacy [13]: Descriptive adequacy refers to the ability to visualize objects in the models. Every defined object should be browse-able, allowing the user to view the structure of an object and its state at a particular point in time. This requires understanding and extracting metadata about objects that will be used to build a visual model of objects and their configurations. This visual model is domain-dependent—that is, based on domain data and objects’ metadata. Descriptive adequacy requires that all of the knowledge representation is visual:

a. Visual models are structured to reflect natural structure of objects and their configurations.

b. All visual knowledge (data and operations) in the visual model is localized.

c. Relationships among objects in the visual model are well defined.

d. Interactions among objects in the visual model are limited and concise.

e. The visual model must transcend objects, and instead highlight crosscutting aspects.

• Understanding adequacy: Understanding adequacy relates to be easy to understand.
• Simplicity adequacy: Simplicity adequacy relates to how simple your models will be.
• Extensibility adequacy: Extensibility adequacy relates to the degree of extensibility, adaptability, customizability, and configurability of your models.
