Which statement best describes data integration?

• A. It provides pre-built data connections to multiple source systems so visualisations can be created quickly once connected.
• B. It cleans and transforms raw data into analytics-ready data
• C. It stores data in a centralized warehouse
• D. It visualizes data in dashboards

Answer: (A)

Data integration centers on linking data from different source systems so it can be used for analysis in one place. When a tool offers pre-built connections to multiple sources, you can quickly connect to those systems, pull in the data, and have the groundwork ready for analytics and visualisations as soon as the data is loaded. This focus on connecting diverse sources and bringing them into a common analytics flow is what makes this description best fit data integration.

For context, cleaning and transforming raw data are steps in data preparation, storing data in a centralized warehouse is data storage/warehousing, and visualising data in dashboards is data visualization.
