说明：  每组不超过4人，每人从TPC-H中选择至少三个查询进行执行，并进行性能调整。同组人员所选择的查询不能相同。各查询均必须包含：两个以上的表连接操作，其包含至少一个聚集函数。 每位同学的该作业均放在一个命名如“姓名-学号-专业-作业1”的目录中 用尽能想到的所有技术方法，使得选定的查询的某些性能指标尽可能的差 用尽能想到的所有技术方法，使得选定的查询的某些性能指标尽可能的好(Each group has no more than 4 people. Each person selects at least three queries from TPC-H to perform and performs performance adjustment. The queries selected by the same group can not be the same. Each query must contain more than two table join operations, which contain at least one aggregation function. Each student's homework is placed in a directory named "name student number professional operation 1". Using all the technical methods that can be thought of, make certain performance indicators of selected queries as poor as possible. Use all the technical methods that you can think of, and make certain performance indicators of selected queries as good as possible.)
