Software architecture attempts to bridge the gap between software requirements and software design

The focus is on solving the problem of a smooth transition from the structure and requirements of a software system to its implementation.1) Software architecture modellingThe primary issue in software architecture modelling is how to represent the software architecture i.e. how to model the software architecture. According to the different focus of modelling the model of software architecture can be divided into five types which are structural model framework model dynamic model process model functional model.
