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? Select the correct answer.
A. The transmission of the data over a wide area network resulted inthe accumulation of additionalmeta 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.
