In one of your online transaction processing （OLTP） applications， most users frequently modify the values， including the key values， of the application tables. Some users generate application reports by using multiple application tables. What is the best table structure that you can use to gain optimal performance？（）A、heap tableB、object tableC、external tableD、clustered tableE、global temporary tableF、indexorganized table （IOT）
考题
Which of the following are not BGRP data structures？ （Choose all that apply.）（）A、EIGRP database tableB、EIGRP CEF tableC、EIGRP neighbor tableD、EIGRP adjacency tableE、EIGRP interface tableF、EIGRP topology table
考题
In your test database， you have created the ORDERS table as an index/x7forganized table （IOT）. To facilitate faster querying， you have created a mapping table and a bitmap index on the ORDER_FILLED column. You observe that the query performance degrades when users perform a large volume of transactions. While investigating the reason， you find that the mapping table segment is fragmented， leading to poor performance. Which option would you use to defragment the mapping table without affecting the original table data？（）A、export and import the mapping tableB、drop and recreate the mapping tableC、truncate the mapping table and reinsert the valuesD、use the ALTER TABLE .. REBUILD command to defragment the mapping table
