Perhaps you should try some spelling variations:
quality processes » quality properties (Expand search), quality practices (Expand search), family processes (Expand search)
database quality » data quality (Expand search), database query (Expand search)
decrease rate » decreased rate (Expand search), decreases rate (Expand search), decrease at (Expand search)
rate decrease » rats decreases (Expand search), rate increase (Expand search), to decrease (Expand search)
in database » in databases (Expand search), _ database (Expand search)
of decrease » or decrease (Expand search), not decrease (Expand search), to decrease (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decrease in database quality processes ) OR ( decrease rate decrease of decrease ))~.
