A DSS is usually built to support the solution of certain problem and does not replace the decision- maker. As such, it is called a DSS application. It is user-friendly with strong graphical capabilities. 8.2.2 DSS components The components of a DSS include a database of data used for query and analysis, software with models, data mining and other analytical tools and a user interface. The DSS database is a collection of current or historical data from a number of applications or groups. It can be small database or a massive data warehouse from a large company, which is continuously being updated. The DSS software system includes software tools for data analysis. They contain various OLAP tools, data mining tools or a collection of mathematical and analytical models. A model can be a physical model, a mathematical model or a verbal model. Most commonly used are the statistical functions such as means, medians, deviations and scatter plots. Optimization models such as linear programming are used to determine optimal resource allocation.
