Drop the tables created in this tutorial.
drop table emp_arch;
drop table emp_arch_copy;
So what’s the use of doing all of this. suppose I have a table that has financial records of my company of last 10 YR. that’s terabytes of data. I don’t want to store such large amount of data in my expensive and finite memory, One thing we can do is move the past 9 yr of data (compress it) at low cost storage(Like TAP) and when we require this data i can get it again thus improving the efficiency of data retrieval.
