Continuous Physical
Database Design
The techniques discussed in Part II are sophisticated and useful in many com-
mon scenarios. However, they take an offline approach to the physical design
problem and still leave significant decisions to database applications (DBAs).
Specifically, DBAs need to explicitly identify representative workloads and
feed them to tuning tools. DBAs are also expected to guess when a tuning
session is needed and when to deploy recommendations. Naturally, this is not
a one-time process, but instead DBAs continuously monitor, diagnose, and
tune database installations.
These manual tasks become even more problematic in current ...
