Software Fortresses: Modeling Enterprise Architectures

Summary

Here are the main points of this chapter:

• The business application fortress design is critical to your overall enterprise architecture.

• Business application fortresses are built on components and component-oriented middleware (COMWare).

• The main benefits of COMWare are automatic transaction boundary management and fortress wall reinforcements through role-based security.

• The automatic transaction boundary management algorithms lead to the golden rule: Component-level methods should be self-contained transactions.

• The golden rule implies that state should be read in and flushed out within the method.

• Components following the golden rule and managing their state correctly will be amenable to high levels of reliability and scale-out scalability ...
