Introduction
Derby stores table and index data in Containers, which currently map to files in the seg0 directory of the database. In the current Derby implementation there is a a 1 to 1 mapping of containers to files. Two containers never map to a single file and 1 container never maps to multiple containers. Should the last sentence be "Two containers never map to a single file and 1 container never maps to multiple FILES"? otherwise it doesn't seem to make sense... Also there are two "a"s in "there is a a 1 to 1 mapping".
