Decision Support Systems (DSS) are computer systems that enable organizations to analyze vast amounts of data obtained from different sources within the organizations.
Typical determinations are monthly sales figures of a current period compared to previous periods, projected revenue numbers,
simulations of price change effects on sales and inventory related data. They aid organizations in making sound business decisions.
A typical DSS implements the following functions:
The TPC has developed three DSS benchmarks, TPC-H, TPC-DS and TPC-DI. All are designed as enterprise class benchmarks. While they cover all three DSS functions, each focus on particular aspects of a typical DSS. TPC-H focuses on ad-hoc reporting, TPC-DS includes elements of ad-hoc reporting and periodic reporting and TPC-DI focuses on the ETL part of DSS.
