Sammendrag
The query optimizer in MySQL chooses from the available query execution plans by estimating the cost of execution for each plan. In this project, MySQL will be extended to record the actual cost of executing each query. By performing queries and analyzing the estimated and actual costs of execution for each query plan, the validity of the query optimizers estimates and choices will be determined.
