Figure 1.6, “Tree changes over time” illustrates a nice way to visualize the repository.Imagine an array of revision numbers, starting at 0, stretching from left to right.Unlike a working copy, a Subversion repository is an abstract entity, able to be operated upon almost exclusively by Subversion's own libraries and tools.As most of a user's Subversion interactions involve the use of the Subversion client and occur in the context of a working copy, we spend the majority of this book discussing the Subversion working copy and how to manipulate it.For the finer details of the repository, though, check out Chapter 5, A Subversion client commits (that is, communicates the changes made to) any number of files and directories as a single atomic transaction.By atomic transaction, we mean simply this: either all of the changes are accepted into the repository, or none of them is.We've mentioned already that Subversion is a modern, network-aware version control system.As we described in the section called “Version Control Basics” (our high-level version control overview), a repository serves as the core storage mechanism for Subversion's versioned data, and it's via working copies that users and their software programs interact with that data.

Each time the repository accepts a commit, this creates a new state of the filesystem tree, called a .Each revision number has a filesystem tree hanging below it, and each tree is a , not individual files.Each revision number selects an entire tree, a particular state of the repository after some committed change.Another way to think about it is that revision N represents the state of the repository filesystem after the Nth commit.When Subversion users talk about Subversion client programs use URLs to identify versioned files and directories in Subversion repositories.Note that this URL syntax works only when your current working directory is a working copy—the command-line client knows the repository's root URL by looking at the working copy's metadata.Also note that when you wish to refer precisely to the root directory of the repository, you must do so using A Subversion working copy is an ordinary directory tree on your local system, containing a collection of files.Each revision is assigned a unique natural number, one greater than the number assigned to the previous revision.The initial revision of a freshly created repository is numbered 0 and consists of nothing but an empty root directory.The file should eventually be updated in order to make it current with the latest public revision.An A typical Subversion repository often holds the files (or source code) for several projects; usually, each project is a subdirectory in the repository's filesystem tree.
