Function of SVN: SVN is a technically safer product, which effectively realizes the combination of system and control. On the one hand, the safety work of the whole system can be effectively distributed to each subsystem, so as to ensure the normal operation of the subsystems, make the subsystems complement each other, and finally ensure the safety of the whole system, and achieve the ultimate goal of pursuing safety through the principle of balance.
Extended data:
SVN server not only has the advantages of data storage that CVS has, for example, information resources will form a resource tree structure after storage, which is convenient for storage, but also has its own characteristics. SVN solved the problem that the same file could not be read and written at the same time in the past through relational database and binary storage, and added its own unique "zero or one" principle.
