Decision Support Systems
TPSs flow through all aspects of an organisation and can provide the information necessary to make informed decisions. Decision support systems (DSSs) assist people to make decisions by providing information, models and analysis tools. For example, a business uses a TPS to process its sales transactions. It uses a database as a DSS to periodically summarise its sales data by date, region and product. This summary information is stored in a separate database to be analysed by senior management. To make decisions, management needs to be able to determine trends in sales quickly by querying the data based on various criteria.
