Dynamic Data Driven Application System

A dynamic data driven application system (DDDAS) is one where data is fed into an executing application either as the data is collected or from a data archive [Dynamic Data Driven Application Simulation#References| [1, p. 662] . The data will then be used to influence the measurements for additional data it may require. Current research for these systems focuses on simulations of physical/artificial/social entities. The simulation can then make predictions about the entity regarding how it will change and what its future state will be. The simulation is then continuously adjusted with data gathered from the entity. The predictions made by the simulation can then influence how and where future data will be gathered from the entity, in order to focus on areas of uncertainty. Intelligent agents will be required to make these decisions with regard to which data to absorb, when it should be absorbed, and how it should be absorbed [Dynamic Data Driven Application Simulation#References| [2, p. 1] . Many of these simulations are inspired by older models used to make predictions about physical systems (i.e. weather forecasting, oil exploration, etc…) [Dynamic Data Driven Application Simulation#References| [1, p. 663] . The term DDDAS was formalized by Frederica Darema around the time of a [http://www.nsf.gov/cise/cns/darema/dd_das/index_wkshp.jsp National Science Foundation (NSF) workshop in March of 2000] [Dynamic Data Driven Application Simulation#References| [1, p. 663] , and is a very new and active area of research [Dynamic Data Driven Application Simulation#References| [3] .
