A typical Internet application usually begins with an architectural diagram. For example, a database connection component might be connected to a data cache, which is accessed by a search engine that is attached to some UI component. When you build an architectural plan, you typically follow several rules:

When the architectural plan is complete, you can implement it with Nucleus and JavaBeans. If you design each component as a JavaBean, you can rely on Nucleus to create, initialize, and establish the relationship between Beans. You can build the components without regard for their initialization values or how their dependencies on other components are satisfied. These application-specific concerns are contained in configuration files that are read and interpreted by Nucleus.
