Abstract
A SQL database tool maps database objects to storage addresses. The SQL database translates SQL requests to I/O requests on specific extents of OS files. A data structure maps the OS file extents to database objects. Using this mapping, I/O requests on files can be correlated to their relevant database objects, providing analysis of I/O activity and I/O wait time for database objects. Based on the computed database object activity level, the database objects may be allocated to different storage tiers according to their I/O needs.
