Why is the use of big data technologies a challenge for medium and small
organisations?
The size of these organizations means that they do not generate large amounts of
data.
1) These technologies are difficult to implement and extremely expensive for
small and medium-sized organizations.
These organizations rarely have the need to access and use big data.
All of the above.
None of the above.
These are sources of unstructured data or weakly structured data: (select all that
apply)
Email messages.
2) Monthly transaction data from the accounting system.
Records of discussions in discussion forum / chats.
Data from employees’ biometric / finger-print clocking.
Social media posts.
3) The four essential qualities that raw data must have are: accurate, complete,
reliable and verifiable.
What is information?
Options:
> Data that is complete, without errors, can be verified and can be used to make
4) decision.
> Processed data that is useful for decision-making.
> Data that can be relied upon due to it being structured and collected through
highly reliable means
> The output of operational, managerial or strategic decisions made by appropriate
level of authority.
, > All of the above.
> None of the above.
Source documents are:
Physical but can also be kept in electronic format on condition that they can be
produced on demand.
5) Absolutely important for the audit process.
Proof that a transaction occurred.
All of the above.
None of the above.
Why is an optical scanner a valuable tool to have for an auditor?
Options:
> Captures date extremely accurate and fast.
6) > Reads handwritten numbers and letters and transfers this information to an on-
line computer.
> Creates time and cost savings in data capturing and information generation.
> All of the above.
> None of the above.
One of the reasons for data migration being necessary is that it is safer to keep
7) parallel data and information systems as backup.
True

What is the correct order of the stages of the data migration process?
Pre-strategy phase; Design phase; Testing phase.

, Schema migration = Letter (C)
Application migration = Letter (E)
Business process migration = Letter (A)
Legacy migration = Letter (D)
Cloud data migration = Letter (B)
A: Often triggered by events like mergers and acquisitions, business optimisation
and reorganisation to attack new markets or respond to competitive threats.
B: Moving information, localhost applications, services, and data to the distributed
computing infrastructure.
C: Necessary when moving from one database vendor to another, or when
upgrading the version of database software being used.
D: Challenging task because of the non-extensibility, incompatibility, and less
openness of the underlying hardware and software of the older systems.
E: Necessary when changing application vendors, for example a new CRM or ERP
platform.
Data quality is the measure of accuracy of data that meets the business

True
False
11) With batch input data is captured periodically in batches while with online input
data is captured immediately into the CIS at the point where the activity occurs.
Big Data refers to:
Data produced by super large organizations that conduct millions of transactions on
a daily basis.
12) Data which is so large that it becomes difficult to store and process using
traditional databases and data processing applications.
Data that, because of its size, can only be stored on multiple databases.
