A Decision Support System (DSS) is designed specifically to assist management and staff in making decisions that are not routine and often complex. It integrates data from various sources and employs analytical tools to provide insights that help users analyze situations and evaluate potential outcomes. This capability is essential for addressing nonroutine tasks, which require specialized information and support in decision-making processes.

A DSS often includes features like modeling, simulation, and data analysis capabilities, enabling users to interactively query data and explore scenarios. This makes it distinct from other systems like Online Analytical Processing (OLAP), which primarily focuses on multidimensional analysis of business data but doesn't specifically cater to decision-making support. Similarly, a data warehouse serves as a centralized repository for large volumes of structured data, while a data mart is a subset of a data warehouse, often focused on specific business areas. Neither of these is specifically tailored for nonroutine decision-making tasks in the way that a DSS is.
