Which systems support decision making by enabling users to extract useful information from large quantities of data?

The correct answer is based on the function of Decision Support Systems (DSS). These systems are specifically designed to help users make informed decisions by providing the tools to analyze large volumes of data. A DSS gathers and processes data from various sources, which can then be manipulated to produce useful information. This information may include reports, visualizations, or analytics, enabling decision-makers to understand complex situations and explore various scenarios.

Unlike other systems, such as Transaction Processing Systems (TPS), which focus on the day-to-day operations and record-keeping of an organization, or Executive Support Systems (ESS), which are more tailored for high-level executives needing summaries of organizational data, the DSS emphasizes comprehensive data analysis and supports the decision-making process at various levels within an organization. Group Support Systems (GSS) also aid decision-making but primarily focus on collaboration among teams rather than extensive data analysis.

Therefore, Decision Support Systems are characterized as tools that provide insights derived from data and help guide users toward informed decision-making, making them the ideal choice in this context.
