Final answer:
The best solution for a business with multiple databases and systems that don't communicate is a centralized database, which consolidates information and enhances data access and analysis.
Step-by-step explanation:
If you have to run a business that relies on information from numerous databases and systems that cannot communicate with each other, a centralized database would be the best component of an enterprise system to address this issue. A centralized database collects data from various sources into a single, comprehensive database. This ensures that all parts of the business have access to the same information, reducing inconsistencies and allowing for better data management and analysis. By integrating disparate systems, the business can harness the full potential of its collective data, making for more informed decision-making and streamlined operations.
