1. How might the use of databases
Revision Exercise 8
in academic records management
align with broader trends in digital
transformation and information
technology?
2. What is a Structured Query
Language? Briefly explain how it
is used to interact with relational
databases.
3. How does a NoSQL database differ
from a relational database in terms
of data structure and flexibility?
4. In what scenario might a NoSQL
database be a better choice
compared to a traditional relational
database?
5. What is a data warehouse, and how
does it differ from a traditional
database in terms of its purpose
and data organisation?
6. Explain the challenges of big
data associated with collecting,
managing, and analysing massive
datasets.
7. Provide an example of how big
data and data warehouses could be
used in a specific industry (such as,
healthcare, finance, education, local
governments).
8. Identify any correlation between
where the user is browsing from and
the specific actions they perform on
the website.
9. Analyse the content of user
messages left on different website
