An OLTP (Online transaction processing) database is a database that allows for quick transaction processing. It involves inserting, deleting, updating data in the database.
OLTP has many drawbacks like if the system fails, all transactions are going to have problems. Also, since multiple users are allowed to access the data, it makes it prone to hackers.
The solution to the problems associated to the OLTP database is the OLAP (online analytical processing) database.

Explanation:
There have been mass extinctions during the Cenozoic as there were during the Mesozoic and Paleozoic, but not as many animals and plants have disappeared. Finally, humanity appeared during the last two million years.The human lineage only diverged from our most recent common ancestor about 5 million years ago; less than half of 1% of that time, and modern Homo sapiens is only between 200,000 and 50,000 years old, depending on your definition.
Answer:
Double newMyDouble = new Double(x);
myDouble = newMyDouble2;
Explanation:
Here the new object newMyDouble is firstly the initial value of said 'double x'. In the second line myDouble is the reassigned the the newMyDouble, which is in fact, the value of x. This exercise helps you understand the syntax of using reference variables in JAVA and their assignment along with reassignment.
