Arcitura Education C90.02 Exam - Topic 6 Question 122 Discussion

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.
B) The data in the relational database was normalized and became denormalized after being exported into a non-relational database.
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.
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.

Totally agree with B! Non-relational databases usually store more data.

I think B is the main reason. Normalization vs. denormalization really affects size.

I’m leaning towards D, thinking that all these factors could contribute to the size increase. It feels like a combination of issues we’ve seen in practice questions.

I feel like option C makes sense too, especially with cloud databases needing to manage state data. But does that really apply to all non-relational databases?

I think we covered something about metadata in our last class. Option A could be a factor, but I wonder if it's significant enough to cause such a large increase.

I remember discussing how normalization affects database size, so option B seems plausible. But I'm not entirely sure if denormalization always leads to a size increase.
