A table space is a storage model that provides a level of indirection between a database and the tables stored within that database. Table spaces allow you to assign the location of database and table data directly onto containers. (A container can be a directory name, a device name, or a file name.) This can provide improved performance, more flexible configuration, and better data integrity.
A single table space can span several containers. For improved performance, each container can use a different disk.
