Problem: Architecture modeling typically establishes a design pattern hierarchy by grouping design patterns and associating them to the related architectural pattern. A similar hierarchy applies to architectural patterns. By grouping and associating patterns in such a way, modelers can create a lattice of patterns referred to as a pattern hierarchy.

To put this concept to work, review the "Catalog of Patterns of Enterprise Application Architecture" (or EAA Catalog). This catalog of patterns is organized functionally. Familiarize yourself with the differences between architectural styles, architectural patterns, and design patterns.

In this Assignment, write a 2- to 3-page paper that addresses the following:

• Create a pattern hierarchy that meaningfully organizes the EAA Catalog of patterns. Include at least one pattern from each category in the catalog.
• Explain the organizing principles you have employed in your pattern hierarchy. As mentioned above, the EAA Catalog is organized functionally. You need to use a different organizing principle.
