Data Distribution Service for real-time systems (DDS) is the OMG publish/subscribe standard that aims to enable scalable, real-time, dependable, high performance and interoperable data exchanges. DDS introduces a virtual global data space where applications can share information by simply reading and writing data-objects addressed by means of an application-defined name (Topic) and a key. Large numbers of publishers and subscribers on DDS can create huge amounts of Topic data. The commonly accepted approach to large-scale real-time data management is to use a database for persistence.
