Q1 QUESTION 1 OF 100
How does data differ from information?
CORRECT ANSWER
Information is output while data is input.
RATIONALE
Data represents raw, unprocessed facts collected from various sources, while information is the interpreted and organized form
of that data, providing context and meaning for decision-making. This distinction highlights the transformation process from
input to output in data management systems.
Q2 QUESTION 2 OF 100
How can an AIS add value to an organization?
CORRECT ANSWER
Improving the quality and reducing the costs of products or services

,What is a potential effect of an Accounting Information System (AIS) that makes information easily accessible and widely
available?
CORRECT ANSWER
It increases pressures for more decentralization and autonomy.
RATIONALE
Easily accessible and widely available information from an Accounting Information System fosters real-time decision-making,
leading to increased demands for decentralized authority as departments seek to leverage data for autonomous operations. This
shift enhances responsiveness and agility within the organization, aligning decision-making closer to operational units.
Q4 QUESTION 4 OF 100
What is the purpose of the referential integrity rule in a relational database?
CORRECT ANSWER
The referential integrity rule ensures that foreign keys, if not null, must have values that correspond to the value of a primary
key in another table.
RATIONALE
Referential integrity maintains consistency across relational database tables by enforcing that foreign keys must accurately
reference existing primary keys, preventing orphaned records and ensuring data integrity. This principle is critical for relational
database design, as it establishes meaningful relationships and supports accurate data retrieval.
Q5 QUESTION 5 OF 100
What is an advantage of using database systems in an organization?
CORRECT ANSWER
Database systems facilitate cross-functional analysis by defining relationships.
RATIONALE
Database systems enable the integration of data from various sources, allowing for relational mapping that supports complex
queries and cross-functional analysis, enhancing decision-making across departments. This relational structure promotes data
consistency and accuracy, critical for informed organizational strategies.
Q6 QUESTION 6 OF 100
Page 3
, Which is a benefit of database technology for organizations?
CORRECT ANSWER
Data integration
RATIONALE
Data integration allows organizations to consolidate disparate data sources into a unified framework, enhancing data
accessibility and accuracy for informed decision-making. This streamlining fosters improved operational efficiency and supports
analytical capabilities across various departments.
Q7 QUESTION 7 OF 100
What is the data processing lifecycle?
CORRECT ANSWER
The operations performed on data to generate meaningful and relevant information.
RATIONALE
Data processing encompasses the systematic operations that transform raw data into meaningful information, involving stages
such as collection, processing, storage, and output. Understanding this cycle is critical for ensuring data accuracy and relevance
in decision-making processes.
Q8 QUESTION 8 OF 100
What is a key advantage of Enterprise Resource Planning (ERP) systems over traditional Accounting Information Systems
(AIS)?
CORRECT ANSWER
ERP systems integrate all aspects of a company's operations with a traditional AIS.
RATIONALE
Integrating all operational facets, ERP systems facilitate real-time data access and collaboration across departments, enhancing
decision-making and operational efficiency beyond the capabilities of traditional Accounting Information Systems, which
typically focus solely on financial data. This holistic approach allows for streamlined processes and improved resource
management throughout the organization.
