The control chart is a graph used to study how a process changes over time. Data are plotted in time order. A control chart always has a central line for the average, an upper line for the upper control limit, and a lower line for the lower control limit. These lines are determined from historical data. By comparing current data to these lines, you can draw conclusions about whether the process variation is consistent (in control) or is unpredictable (out of control, affected by special causes of variation). This versatile data collection and analysis tool can be used by a variety of industries and is considered one of the seven basic quality tools.

Quest SQL Optimiser validates database code to ensure the best-possible performance by helping you proactively identify potential issues and automate the SQL optimisation process. The SQL Server Query Optimizer is a cost-based optimizer. It analyzes a number of candidate execution plans for a given query, estimates the cost of each of these plans and selects the plan with the lowest cost of the choices considered. Indeed, given that the Query Optimizer cannot consider every possible plan for every query, it actually has to do a cost-based balancing act, considering both the cost of finding potential plans and the costs of plans themselves.
