Use the built-in database export/import commands (or in the case of Access, copy the file). There's no such tool that will magically dump your database into a file format because database organization may be extremely complicated, especially the more your data is normalized.
For example, let says instead of US States in an address table, you have a StateId which refers to a record in a States table. How should such data be dumped? Should the Address print "New York City, 19" or "New York City, NY" which the ID resolved? You'd probably want the second one, but computer dumps aren't smart enough to handle such a case naturally. In other words, databases are structured and dumps (or flat files) are not, therefore the process of developing a 1-to-1 mapping is non-trivial unless you rely on built-in SQL commands
