A decision support system (DSS) is a computer-based tool that helps individuals and organizations make informed decisions. It combines data, sophisticated analytical models, and user-friendly software to analyze complex information. DSS can be used in various fields, such as business, healthcare, and agriculture, to improve decision-making processes. These systems often utilize data from multiple sources, including databases and external information, to provide insights and recommendations. By presenting data in a clear and organized manner, a DSS enables users to evaluate different scenarios and outcomes, ultimately leading to better choices and strategies.
