These systems include file drawer and management reporting systems, data warehousing and analysis systems, Executive Information Systems (EIS) and Spatial Decision Support Systems.
The first generic type of Decision Support System is a Data-Driven DSS. They don’t have to have a theory or model but can “free-flow” the data. Data-Driven DSS take the massive amounts of data available through the company’s TPS and MIS systems and cull from it useful information which executives can use to make more informed decisions.Decision support systems have a definite structure in businesses, but in reality, the data and decisions that are based on it are fluid and constantly changing.
#DSS VS BI UPDATE#
For instance, many companies constantly download and analyze sales data, budget sheets and forecasts and they update their strategy once they analyze and evaluate the current results. While many people think of decision support systems as a specialized part of a business, most companies have actually integrated this system into their day to day operating activities.
DSS are interactive computer-based systems and subsystems intended to help decision makers use communications technologies, data, documents, knowledge and/or models to successfully complete decision process tasks. By combining massive amounts of data with sophisticated analytical models and tools, and by making the system easy to use, they provide a much better source of information to use in the decision-making process.ĭecision Support Systems (DSS) are a class of computerized information systems that support decision-making activities. Decision Support Systems (DSS) help executives make better decisions by using historical and current data from internal Information Systems and external sources.
