Which data quality dimension refers to how accurately data reflects the real-world entities it represents?
Answer: Accuracy
Accuracy measures whether data values correctly represent the true state of the real-world objects or events they describe.
What is the function of an Extract, Transform, Load (ETL) process in data management?
Answer: To move and convert data from source systems into a target repository like a data warehouse
ETL extracts data from source systems, transforms it to meet target specifications, and loads it into a destination system such as a data warehouse.
Which concept describes the full journey of data from its origin through all transformations to its final destination?
Answer: Data lineage
Data lineage traces the origin, movement, and transformation of data over time, providing transparency and supporting data quality and compliance efforts.
What distinguishes SaaS from IaaS in cloud computing service models?
Answer: SaaS delivers ready-to-use applications over the internet; IaaS provides virtualized infrastructure resources
SaaS delivers fully managed applications (like email or CRM), while IaaS provides virtualized compute, storage, and networking resources for users to build on.
In information systems design, what is the purpose of a data dictionary?
Answer: To define the meaning, format, and usage rules for each data element in a system
A data dictionary documents metadata about each data element — including its name, definition, data type, allowed values, and relationships — ensuring shared understanding.
Which technology uses mathematical algorithms to discover patterns in large datasets without explicit programming?
Answer: Machine learning
Machine learning algorithms learn from data to identify patterns and make predictions or decisions without being explicitly programmed for each scenario.
What is the primary goal of information lifecycle management (ILM)?
Answer: To manage information from creation through active use to final disposition at the lowest appropriate cost
ILM aligns storage tiers, retention policies, and disposition schedules with the changing value of information over time to optimize cost and compliance.
