2. CVS, the acronym for Concurrent versions System, is a great masterpiece of the Open source software world and is widely used in small and medium software enterprises worldwide because of its simplicity, power, cross-platform, concurrent versioning, and free of charge. Its biggest regret is the lack of appropriate technical support, many problems need to find their own data, or even read the source code. CVS is a typical server/client-side software, with UNIX versions of CVS, Linux versions of CVS, and Windows version of CVS, which already contains the server and client side of the download package. But since we are generally working with Windows operating systems, we can then download a client-side software Wincvs for Windows CVS.

6. CCC Leon Presser, of the University of California in the early 70, wrote a paper proposing the concept of controlling change and configuration, and then in 1975 he set up a company called Softtool, which developed his own configuration management tool: CCC, This is also one of the earliest configuration management tools.

7. Borland Starteam An integrated environment for managing configurations and changes. Main features: Improve communication and performance of decentralized development team, improve observation and control of application software development Lifecycle, leverage existing technology investments and increase ROI, and tailor solutions to meet agency requirements. Starteam is compatible with the Microsoft Source Code Control Interface (API), enabling seamless integration with numerous tool platforms that support the interface. Starteam can also integrate with specific development tools, such as Microsoft, IBM, and Borland, including Borland JBuilder, Borland Delphi, Borland C + + Builder. Starteam can also integrate with a number of third-party software to give full play to the existing investment value of development agencies for activities such as development, testing, and requirements.
