These are two different entities. While OLTP is a type of
data base organisation, DSS is a mathematical methodology.
OLTP contains transactional data and in contrast to it,
historycal data are contained in OLAP i.e. data
warehousing. In contrast to that, DSS can benefit from both
OLAP and OLTP. The main strength of DSS is a possibility to
use subjective reasoning of decision maker, in order to
make a decision. As a data foundation for DSS one can
utilize OLAP, OLTP or just its own logic and experience.
