Progress in whole-lifecycle software architecture modeling
The gradually increasing complexity of user requirements and runtime environments of software demands software to be of more capabilities and thus become more complex than ever. In the past several decades, there was a trend that the scale of software has been increasing continuously. Nowadays, there are tens or even hundreds of million lines of code in a large scale software system. For example, the Windows operating system scales from 15 million lines of code in 1995 to 60 million lines of code in 2007; in 2011, the scale of software in BMW 7 Series reaches 200 million lines of code; the scale of software in Airbus 380 even reaches 1 billion lines of code. When the scale and complexity of software is beyond what developers and techniques can control, the quality and efficiency of software would fail to satisfy user requirements, leading to the phenomena of software crisis.
