Software architecture(SA) acts as blueprint and skeleton of software.It's an availability approach for people to grasp whole macroscopical architecture and evolution of software based on SA.Firstly

for aim of static evolution of SA

SA relation matrix and reachability matrix are created.Depending on matrix shift calculation

ripple effect of SA evolution can be analyzed and its quantity can be ascertained.At the same time

an approach for calculating relative quantity of component effect is shown.Secondly

for aim of dynamic evolution of SA

SA dynamic semantic network model is described

convergence condition of soak process in this SA dynamic semantic network model is addressed.A concept of atomic filtration of adjacency matrix is put forward

so SA dynamic evolution is expressed by a series of continuous atomic filtrations of adjacency matrix.An analysis framework of ripple effect of SA evolution based on two of levels is proposed.All are credible foundation to manage

control

utilize

value SA evolution

and describe SA evolution with quantity.
