-oriented design).The introduction of abstract modules with indirect functions can not only reduce the interdependence and influence between modules, but also make the responsibilities of each module clearer and more exclusive, thus making the whole system more conform to the requirements of low coupling and high cohesion. However, the indirect principle can not be abused, excessive indirect layer will sacrifice the simplicity of the system or runaway performance for standby, in practice must we
