range partitioning for manageability is to support

warehouse. When, for example, a DBA loads new
data into a table on a weekly basis, that table

simply the addition of a new partition.

For several releases, SQL Server had the ability to
automatically tune itself based on run-time conditions. As a
result, SQL Server requires little, if any, tuning by a
database administrator; memory, file sizes, and the I/O
subsystem are a few of the items SQL Server manages on
behalf of the administrator.
Oracle has only just begun to explore this area with the
addition of wizards in its management tools. SQL Server
first implemented wizards over six years ago and is years
ahead of other vendors with its dynamic automated
resource management and tuning capabilities. Additionally,
many management tools and utilities that come as standard
