Software Configuration Management Tools In The Development Of Large Sites

With the rapid evolvement of information technology, software development are widely used in advanced technologies and products industry. However, when advanced operating system and development tools bring high returns to the enterprise, our development environment becomes more and more complexed, even it is difficult to be managed. This situation will result in the team communication difficulties, low software reuse rate, high code redundancy, lack of documents and other issues, which may caused loss of data, the long development cycle, low product reliability, poor quality, software maintenance difficulties, user complaint and increased risk of projects.As an important process in the software development, software configuration management is more and more recognized by the company. One successful software configuration management requires appropriate management process and tools. Clearcase is currently the most extensive enterprise-level, cross-platform configuration management tools, it's mainly based on Windows and UNIX development environment to support complex cross-platform software development, it can be closely integrated with IBM's other software tools such as Clearquest, Rose. It can also work seamlessly with Windows Explorer and other development tools like JBui lder, IBM WebSphere Studio etc. Therefore, clearcase which used in large transactions web development, not only can track the entire process of website development, saving all status for development to extract at any time, but also simplifies the configuration management in development process, and provide support for those geographically dispersed projects.The paper firstly discuss the current status and issues of site development and necessity of the clearcase based software configuration management. Base on this, discuss which practice activities are mainly used in clearcase implementation, and how to customize the set of own development mechanisms and process in large enterprises.Paper will also give the details about how the developers work on one module and different changes to same code at the same time, even multi-site development team can work together without disturbing each other.
