Abstract:This paper makes an in-depth study on the system structure of SVN,and gives a specific method to realize source code management of meteorological project by using SVN technology.This paper divides SVN technology into two modules,which are server and client.The server selects Apache Subversion to set up the SVN server,and the configuration of the SVN source code warehouse is deeply analyzed to realize the management of the source code warehouse.The client selects SVN command line,TortoiseSVN,Subclipse for the study,and providing the specific methods to check out,modify,update,submit,rollback,branch,and merge the source code with SVN client,which could realize the centralized storage of source code of each meteorological project,improve the management ability of meteorological project and improve the efficiency of project development.
