Question 10

We exported data from our on-premise relational database to a cloud-based non-relational database.
After the export, we noticed that the size of the cloud-based database was significantly larger than
our on-premise database. What is the likely reason that the database size increased?

  • A. The transmission of the data over a wide area network resulted in the accumulation of additional meta data from HTTP headers that was stored in the non-relational database, resulting in the increase in data received by the cloud.
  • B. The data in the relational database was normalized and became denormalized after being exported into a non-relational database.
  • C. In order to support higher levels of scalability, the cloud-based database is required to add state data to the non-relational data it stores. This state data is used to synchronize instances of the database tables during runtime usage, but also increases the size of the overall database.
  • D. All of the above.
Answer:

B
