Dependency Management Techniques
Why is software so difficult to change? When you establish your initial vision for the software’s design and architecture, you imagine a system that is easy to modify, extend, and maintain. Unfortunately, as time passes, changes trickle in that exercise your design in unexpected ways. Unlike what you had anticipated, each change begins to resemble nothing more than another hack, until finally the system becomes a tangled web of code that few developers care to venture through. Eventually, modifications to the software intended to improve the system have the opposite affect of breaking other parts of the system. The software is beginning to rot.
The most common cause of rotting software is tightly coupled code with a heavy dependency graph. This session explores the most common symptoms of rotting design, examine their root cause, and present techniques and patterns that have been used on a number of real world projects to help manage dependencies across classes, packages, and the binary units of deployment.
