Answer to Question 1

Architecture is about composition. When we think about architecture, we must think how things are connected, not what we will end up with if we decompose the structure. Coupling is the extent of dependency among the components from which the system is composed. Generally, a loosely coupled system has advantages over a tightly coupled one, but other factors such as structural strength, performance, maintenance, and cost should be taken into account as well. To loosen coupling in software, we can use certain mechanisms that we have discussed in previous chapters: signal events, abstract interfaces, component-based architecture, and patterns such as the object adapter.
